Happy Birthday, Andy Cohen! The king of Bravo celebrated his 50th birthday in style on Sunday’s Watch What Happens Live With Andy Cohen, and was surprised when his longtime pal, John Mayer, showed up to host the special episode alongside with some of his other close friends, who acted as bartender throughout the episode. The 40-year-old singer-songwriter kicked things off by covering one of Cohen’s favorite Diana Ross songs, “It’s My House.” Cohen jammed out to Mayer’s soulful rendition, which the singer admitted, “I have done nothing but learn that song in the last 48 hours. I have ate, breathed and slept ‘It’s My House,' and I am now a fan of that song!” Mayer wasn’t the only one who serenaded the birthday boy. Cohen also got a surprise call from music legend Dolly Parton, who jokingly agreed with the late-night host that her 1977 song, “Me and Little Andy,” was actually written about him. “I’m a huge fan of yours and I didn’t want to miss the chance to say ‘Happy Birthday’ to my favorite Little Andy!” the 72-year-old country crooner declared after singing a verse of “Me and Little Andy” over the phone. Cohen and Mayer reflected on their tight knit friendship and even addressed rumors of a secret romance between them. “Do you think people wonder if we’re in a secret relationship? We get a lot of nods from behind the bar,” Mayer quipped after Cohen declared, “I feel like I know your body too.” Cohen laughed as his pals nodded and tried to give Mayer a high-five. “See, I tried to give you a straight high-five and you gave me a gay [handshake],” Cohen laughed. “My nails are still wet!” Mayer joked. Later, when Cohen was talking about convincing certain celebrities to be on his show, he replied, “I’m always trying to turn them.” Mayer added, “Believe me, I know you like trying to turn people.” At the end of the show, Cohen graciously thanked Mayer for hosting and being there. “To you, we’ve said I love you a thousand times, but just honestly, you’re getting ready for the Dead [& Company] show, ‘New Light,’ the video came out today, I absolutely cannot believe that you put yourself on a freaking plane [to be here],” Cohen said. “I really do feel like we have had a glorious time together, but this last year has been like a victory lap of love and that you did this for me is blowing my mind.” Mayer further posted several birthday Instagram messages for his pal, including: “I love you, and you are such a special person that I’m sure you are known throughout the universe.” For more on Mayer and his dating life, check out the clip below: John Mayer Reveals the New Song About an Ex That Makes Him So Sad He Can't Perform It Live This video is unavailable because we were unable to load a message from our sponsors.

The singer celebrated the happy occasion by bringing a group of friends — including Cohen and Bob Saget — to Brazil. “This right here is an ELECTRIC COWBOY! They only made one @johnmayer,” Cohen captioned a photo of the pair sitting side by side. “We are lucky to have him. Happy Birthday 💗⚡💗⚡. #JM40.” Cohen later shared a second tribute for the birthday boy, adding, “My heart is busting out with a whole lotta feels after an experience of a lifetime. Brazil is Magic and so are you, JM.” As an extra special birthday gift, this year Mayer surprised Cohen by taking over hosting duties on a birthday edition of Cohen’s Bravo show. The celebrations included cake, balloons, an embarrassing dive into Cohen’s vault of personal videos, a special serenade and a few jokes about the pair’s bromance.

The “Your Body Is a Wonderland” singer, 40, told Andy Cohen that the “Red Sparrow” actress, 27, avoids him at all costs: “You have a lot of friends who, without you, would want nothing to do with me — and I find that exciting! You know what I mean? You’re friends with Jennifer Lawrence, who just doesn’t want anything to do with me. Look, I don’t have the world’s greatest track record when it comes to celebrity relationships, so it’s amazing to watch your friends humor me on a friend level, but also keep a fair distance from me.” He continued, “It’s really, really fun, because if you are someone who cares about your image — and you take this job because it looks right, you don’t take that job — dating John Mayer at this point is conceptually just sort of a no-no. So, it’s really fun to get to hang out with your friends — A-list star friends — who otherwise would be highly uncomfortable sitting around me. And I want to thank you for that.” “I want them to see you in the new light that I see you,” Cohen, 50, smiled back at Mayer, referencing his new single. “Slowly but surely I’m setting myself up for another disastrous celebrity relationship so that I can wake up a month later and be back 10 years in time. You know what I mean? Like, leave everything as you found it, Andy. That’s what I say!” Mayer joked. Mayer was hosting “Watch What Happens Live with Andy Cohen” for Cohen’s 50th birthday show, as the two are close friends. Lawrence is an avid Bravo fan and even unintentionally started a feud with “Vanderpump Rules” star Lala Kent. Reps for Mayer and Lawrence didn’t immediately get back to us.<doc-sep>
Bravo John Mayer swapped seats with bestie and birthday boy Andy Cohen on Sunday night's "Watch What Happens Live," which was dedicated entirely to the talk-show host's golden year. The inside jokes and banter flowed effortlessly between the longtime friends. Then John asked Andy to name a celebrity he's still salty about having turned down an appearance on "WWHL." "Oh, wow, there are so many," Andy said. "I'm always wanting to turn them. You know what I mean?" "Believe me, I know you like trying to turn people," John replied with a grin. Andy said he wished he had his earpiece in so that his staff in the control room could help him out. John, who was wearing the earpiece, blurted out, "Michelle Obama!" "Michelle Obama! Yes, absolutely, yeah," Andy replied. "I've given so much money. I've participated with them. I'm an enthusiast. I'm ready!" John and Andy then bonded over having recently smoked pot with "Game of Thrones" novelist George R. R. Martin, which prompted Andy to brag about the other famous stoners who made his "amazing" pot list: Willie Nelson, Snoop Dogg and Bob Weir from Grateful Dead. John then posed the evening's second-most daunting question: "You can only have one for the rest of your life: weed, oral sex or cheese." "I love cheese, but I'm taking that off the list," Andy said before reaching the conclusion that he couldn't live without oral sex. Of his beloved marijuana, Andy said he'd "have to find another vice." The evening's most daunting question followed: "If you had to choose one of your BFFs to be stranded on an island, who would it be: Sarah Jessica Parker, Kelly Ripa, Anderson Cooper or John Mayer?" "I'm going to pick Anderson, and here's why," Andy said. "He is a catastrophist. There was a moment a year ago or 8 months ago where I thought we were gonna be in a nuclear holocaust, and I was talking to him about it, and he understood what the world would be in that situation in a way that I had never thought about. And he had so many survival techniques, so I actually think that he could keep us alive the longest." Andy then gave a heartfelt thank you to his staff, his viewers and his dear friends for what he called "9 years of glory" on Bravo's late-night platform. In another delightful moment, John thanked Andy for introducing him to famous people who would otherwise want nothing to do with him because of his star-studded list of exes. "You have a lot of friends who, without you, would want nothing to do with me -- and I find that exciting," John said. "You know what I mean? You're friends with Jennifer Lawrence, who just doesn't want anything to do with me. Look, I don't have the world's greatest track record when it comes to celebrity relationships, so it's amazing to watch your friends humor me on a friend level, but also keep a fair distance from me." "It's really, really fun, because if you are someone who cares about your image -- and you take this job because it looks right, you don't take that job -- dating John Mayer at this point is conceptually just sort of a no-no," the singer added. "So, it's really fun to get to hang out with your friends -- A-list star friends -- who otherwise would be highly uncomfortable sitting around me. And I want to thank you for that."
