After Jason Alexander revealed why the showrunners killed off his fiancee in "Seinfeld," adding that it was hard to "play off" actress Heidi Swedberg, he took to Twitter today to apologize. 
 
 "Ok folks, I feel officially awful. Yesterday on @Sternshow, I retold a story I had told years ago about my personal difficulties and insecurities in playing George against the Susan that Heidi Swedberg created. The impetus for telling this story was that Howard said, 'Julia Louis Dreyfuss told me you all wanted to kill her' So I told the story to try and clarify that no one wanted to kill Heidi." 
 
 Swedberg played Susan Ross, George's fiancee, who eventually dies by poisoning after licking all the envelopes on their wedding invitations. 
 
 "And again I say, I and the cast really liked and like Heidi. She is a kind, lovely person who undoubtedly worked really hard to create Susan and that character was clearly what Larry and Jerry wanted her to be for George. I just felt I was on uncertain ground in how to play off that character and I was always concerned that it wasn't working. And that's what I would voice concern about. But because the scenes were playing the way they were, the relationship with George and Susan sustained a whole season. People clearly liked the interplay even though I believed I was 'off,'" he continued. 
 
 "Larry and Jerry were not sure how that relationship would end. They didn't really want George married but all the alternatives seemed predictable. They were always looking for an inventive end to the engagement. So when the comment was made about 'killing', no one was talking about the actress - they were talking about the character. And that made a creative light bulb go off apparently," he wrote. 
 
 But Alexander didn't want to put the burden of the character on Swedberg. 
 
 "Heidi would always ask if there was anything in the scenes she could do or if I had any thoughts. She was generous and gracious and I am so mad at myself for retelling this story in any way that would diminish her," he added. "If I had had more maturity or more security in my own work, I surely would have taken her query and possibly tried to adjust the scenes with her. She surely offered. But, I didn't have that maturity or security. And, Larry and Jerry would probably have killed me as it was all playing exactly as they wanted. Clearly Susan and George were coming off just the way they wanted." 
 
 He closed by personally apologizing to the actress and writing, "You are a sweetheart. I actually launched into this on Stern to defend you. But this is why I'm not a lawyer." 
 
 This apology came after Alexander explained the back story to one of the show’s key moments during a Wednesday appearance on “The Howard Stern Show.” 
 
 Alexander appeared on the show ahead of his turn in the Broadway comedy “Fish in the Dark,” replacing Larry David, the co-creator of “Seinfeld.” 
 
 The seventh season of “Seinfeld” features an arc involving George’s engagement. George is initially optimistic about the engagement, but later seeks to sabotage the relationship by taking up smoking, asking for a prenuptial agreement and pursing a coffee date with actress Marisa Tomei. 
 
 In the season’s final episode, “The Invitations,” Susan dies after licking poisonous, inexpensive envelopes for their upcoming wedding, a nod to Costanza’s stinginess, and symbolizing the relationship’s toxic impact on Susan’s life.

 According to Alexander, 55, the deadly finale was borne from the actors’ troubles to connect. 
 
 “I love [Swedberg]. She’s a terrific girl. I love her … I couldn’t figure out how to play off of her,” Alexander told Stern. “Her instincts for doing a scene, where the comedy was, and mine were always misfiring. And she would do something, and I would go, ‘OK, I see what she’s going to do, I’m going to adjust to her,’ and then I’d adjust, and she’d change. 
 
 “I had done three episodes with her, and Larry calls me up at the beginning of the season and goes, ‘Good news: I’ve got a great arc for you this season – you’re gonna get engaged.’ Oh, that’s great! Who do I get engaged to? Susan. And I went, ‘Oh, great. Who’s playing George?’ Because it was such a disaster,” Alexander said. 
 
 Following filming, Alexander said, the core cast would go to dinner, and Alexander complained about his lack of chemistry with his on-screen fiancee. Initially, Alexander said, his fellow stars Julia Louie-Dreyfus and Jerry Seinfeld brushed aside his concerns. But after they started sharing scenes with Swedberg, they too acknowledged similar issues , and openly pondered the character’s fate, Alexander said. 
 
 “Julia said, ‘I know, don’t you want to just kill her?’ And Larry went, ‘Kebang,’” Alexander said. 
 
 “Every time I tell this story, I cringe,” Alexander admitted to Stern. “Heidi is the sweetest.” 
 
 Following Swedberg’s arc as Susan, she continued picking up acting roles, appearing in such shows as “ER,” “Gilmore Girls” and “Bones.” These days, the Hawaii native plays and teaches ukulele music and performs as the lead in the Sukey Jump Band. ||||| Angry Alec is @ it again — but this time, not on Twitter. 
 
 The same day he deactivated his Twitter account, Alec Baldwin used The Huffington Post to rant yesterday against an American Airlines flight attendant who failed to be awed by his stardom. 
 
 A day after he was booted from an LA-to-JFK flight for freaking out because a crew member told him to turn off his phone, Baldwin last night apologized for delaying his fellow passengers — but resumed his verbal attack on the flight attendant. 
 
 “I was singled out by this woman in the most unpleasant of tones. I guess the fact that this woman, who had decided to make some example of me, while everyone else was left undisturbed, did get the better of me,” Baldwin wrote about the flight attendant on the Huffington Web site. 
 
 “The lesson I’ve learned is to keep my phone off when the 1950s gym teacher is on duty. That was my fault there, even though this trip was quite a bit different from so many others.” 
 
 The loudmouth Capital One spokesman — he plays a pampered passenger getting the most out of his frequent-flier miles in the bank’s ads — first used the words “gym teacher” to describe the airline employee in a series of tweets after he was thrown off the flight. 
 
 It’s not the first time the actor has tried to publicly humiliate a worker who ticked him off. On Sept. 7, Baldwin badmouthed a man making his coffee at Starbucks. 
 
 “Starbucks on 93 and B’way. Uptight Queen barrista [sic] named JAY has an attitude problem,” he tweeted. 
 
 But unlike the coffeehouse giant, American Airlines stood up to the bullying Long Island native, calling Baldwin “rude” for using “offensive language.” 
 
 “The passenger ultimately stood up [with the seat-belt light still on for departure] and took his phone into the plane’s lavatory,” AA said on Facebook. “He slammed the lavatory door so hard, the cockpit crew heard it and became alarmed, even with the cockpit door closed and locked. They immediately contacted the cabin crew to check on the situation. 
 
 “The passenger was extremely rude to the crew, calling them inappropriate names and using offensive language.” 
 
 Baldwin, 53, used his spare time yesterday to again trash the airline and its attendant, saying he was persecuted because of who he is. 
 
 “In this case, while other people were still manipulating their own phones, this one employee singled me out to put my phone away,” Baldwin whined. 
 
 A witness to Baldwin’s tirade said the “30 Rock” star dropped an F-bomb at the flight attendant. 
 
 “ ‘I want your f–king name right now!’ ” he allegedly screamed. 
 
 After that outburst, Baldwin went into the restroom and pounded the walls before coming out to challenge a group of flight attendants, including the original target of his fury. 
 
 “When he cornered the other flight attendants after the bathroom tantrum, he screamed, ‘I want that woman’s name right now!’ ’’ a witness told The Post. 
 
 “Both times, she [Baldwin’s flight-attendant target] said, ‘You can copy it from my name tag.’ ” 
 
 Later Baldwin deactivated his popular Twitter account, leaving his 600,000 followers in the dark. 
 
 In one of his last tweets, Baldwin wrote, “Let’s play a game called Mass Unfollowing. I want to crash this acct and start again.” 
 
 Baldwin’s rep said he didn’t know when or if the raging actor would be back on Twitter. 
 
 Baldwin insisted he was merely playing the online game Words with Friends while the plane was on the ground. 
 
 Words with Friends maker Zynga lapped up the attention, as the game enjoyed a huge spike in popularity following Baldwin’s tirade. 
 
 The Scrabble-esque time killer had 5.5 million Facebook users yesterday, up from 5.2 million on Saturday and Sunday.. ||||| Oh dear God, leave Heidi alone 
 
 Ok folks, I feel officially awful. Yesterday on @Sternshow, I retold a story I had told years ago about my personal difficulties and insecurities in playing George against the Susan that Heidi Swedberg created. The impetus for telling this story was that Howard said, "Julia Louis Dreyfuss told me you all wanted to kill her". So I told the story to try and clarify that no one wanted to kill Heidi. 
 
 
 
 And again I say, I and the cast really liked and like Heidi. She is a kind, lovely person who undoubtedly worked really hard to create Susan and that character was clearly what Larry and Jerry wanted her to be for George. I just felt I was on uncertain ground in how to play off that character and I was always concerned that it wasn't working. And that's what I would voice concern about. But because the scenes were playing the way they were, the relationship with George and Susan sustained a whole season. People clearly liked the interplay even though I believed I was "off". 
 
 
 
 Larry and Jerry were not sure how that relationship would end. They didn't really want George married but all the alternatives seemed predictable. They were always looking for an inventive end to the engagement. So when the comment was made about "killing", no one was talking about the actress - they were talking about the character. And that made a creative lightbulb go off apparently. 
 
 
 
 But in telling this story, it sounds like we are putting a heavy burden on Heidi. I, personally, am not. Heidi would always ask if there was anything in the scenes she could do or if I had any thoughts. She was generous and gracious and I am so mad at myself for retelling this story in any way that would diminish her. If I had had more maturity or more security in my own work, I surely would have taken her query and possibly tried to adjust the scenes with her. She surely offered. But, I didn't have that maturity or security. And, Larry and Jerry would probably have killed me as it was all playing exactly as they wanted. Clearly Susan and George were coming off just the way they wanted. 
 
 
 
 So, to all the press that is now running wild with this 15 year old story, please don't pervert it. No one told Heidi to do anything different - and she surely would have, if asked. And no one that I am aware of, including myself, didn't like her. And now with distance, I can look at those episodes and see that there was a fun relationship there between George and Susan. It works perfectly. I simply couldn't see it or find it at the time. 
 
 
 
 To Heidi, I personally apologize. You are a sweetheart. I actually launched into this on Stern to defend you. But this is why I'm not a lawyer. Now everybody, calm down and just enjoy the reruns and think, "why did he think this wasn't working? This is great."
