Olivia Munn is pregnant!

The Love Wedding Repeat actress is expecting her first baby with John Mulaney, the comedian revealed Tuesday during an appearance on Late Night with Seth Meyers.

"You've had a year," Meyers, 47, told Mulaney at the top of the evening, to which the comedian replied, "I packed a lot into this... Is it September now? I went to rehab in September, I got out in October, I moved out of my home from my ex-wife [Anna Marie Tendler]..."

"Then in the spring I went to Los Angeles and met and started to date a wonderful woman named Olivia," he continued.

While thanking Meyers for having him on the show, Mulaney said, "Olivia and this baby have helped save me from myself in this early journey out of recovery."
