– Alec Baldwin got his marriage license today, but it wasn't all flowers and romance: Upon leaving New York City's Marriage License Bureau, he punched a New York Daily News photographer in the face, the paper claims (and it has photos of the encounter). Marcus Santos was "standing innocently," according to the newspaper, when an angry Baldwin approached and told him to move back. Baldwin then allegedly grabbed another photographer also standing there, Santos told him to let go, and you can imagine the rest. "He comes after me, starts shoving and punching me—one time, right in the chin," Santos says. A witness says Baldwin was indeed "crazy," but sources tell TMZ Baldwin simply pushed Santos after the photog nearly hit him with his camera; that's the story Baldwin himself gave on Twitter, before classily ending his tweet with the hashtag "#allpaparazzishouldbewaterboarded." He later tweeted, "I suppose if the offending paparazzi was wearing a hoodie and I shot him, it would all blow over..." More intrigue: Gawker implies Baldwin may actually have gotten married, rather than simply obtained his license. (Click to see which other celeb troublemaker had a more peaceful wedding yesterday.)
