Mulaney, Munn expecting a baby

During an appearance on Seth Meyers’ show Tuesday night, John Mulaney cheerfully broke down what a roller coaster year he’s had: The stand-up comedian left drug rehab last October, broke up with his wife, hosted “Saturday Night Live,” relapsed on drugs, went into rehab again until February, and checked into a sober living house. Mulaney, 39, confirmed reports about major changes in his personal life. He is dating TV and film actor Olivia Munn, 41. But there’s more: “We’re having a baby together,” Mulaney said. “I’m gonna be a dad!”
