Olivia Munn and John Mulaney got married in a small, private ceremony at a friend's home in New York over the Fourth of July weekend. The ceremony was officiated by Munn's The Newsroom co-star Sam Waterston, and only their 2-year-old son Malcolm and a witness were present. The couple, who started dating in 2021 following Mulaney's divorce, welcomed their son in December 2021. Munn recently revealed her battle with bilateral breast cancer, for which she underwent multiple surgeries, including a double mastectomy and reconstructive surgery. Despite these challenges, the couple have remained supportive of each other through Munn's health journey and parenting. This is Munn's first marriage and Mulaney's second.
