Olivia Munn and John Mulaney went from one of Hollywood’s most buzzed about couples to a pair of happy parents, trying to keep things on the private side. The A-listers, who are believed to have started dating in the summer of 2021, were first socially connected a few years ago and have stayed friends. When John checked into a rehab center for a 60-day stay in December 2020, Olivia took to Twitter to send him well wishes. In May 2021, John announced he and his wife of almost seven years, Anna Marie Tendler split several months prior. Shortly afterward, rumors began to swirl that he was dating Olivia, and the pair were snapped together for the first time on June 26, 2021. The couple announced they were expecting a child together in Sep. 2021 and welcomed son Malcolm in Nov. 2021.
