The actress and the comedian have been linked romantically since May 2021 after he separated from his wife and, in September, it was revealed Olivia is expecting a child with Mulaney ahead of break-up rumours.
But Munn refuses to comment on her personal life, telling the Los Angeles Times, "It's definitely not foreign for me to have people speculate incorrectly about things and to have rumours run rampant in one way. They (people) think they know our relationship so well. When in reality, they don't. There's no way anyone could know what any of his relationships were or what our relationship is."
"I've chosen not to refute specific claims (because it will) feed into a narrative that's just not true... If I try to say anything, I run the risk of being called messy or not telling the truth. The only way to win, for me, is to pull back and to not play the game at all."
Meanwhile, Olivia Munn has been open about her journey to motherhood. She admitted she was nervous about becoming a first-time mother.
She is also dealing with body image issue that triggers her past insecurities as her baby bump is growing bigger.
She previously said, "It's just so hard because I will Google search 'street wear maternity', and a lot of it comes up with these gorgeous women who are super skinny, and have this little bump, and everything is effortless."
