John Legend closed out 2012 by celebrating his 34th birthday in Las Vegas on Sunday. The singer performed at club Haze, where we’re told he was drinking champagne between songs as female fans near the stage tried to get his attention. A witness said, “Women were screaming,” but his fiancée, Chrissy Teigen, stepped in: “She kissed him as soon as he got back to their table. She even wiped sweat off his face with a napkin and gave him a kiss before going back to champagne with friends.”
