Olivia Munn and John Mulaney have kept their relationship low key since romance rumors first began in May 2021. Reports of the coupling came a few months after John completed a 60-day stint in rehab in December 2020, and three days after the comedian’s rep confirmed that he split from his wife. While the timing has raised some eyebrows, there’s no doubt the two Hollywood stars are going from strength to strength as they welcomed their first baby together last November. Let’s take a deep dive into Olivia and John’s relationship timeline, which starts all the way back in 2015, below.

2015: Olivia Gushes about John

Olivia and John had a fateful meeting at Seth Meyer’s wedding, where the X-Men actress chatted up the Saturday Night Live comedian and his then-fiancée Anna Marie Tendler. We were at a wedding together and I was like, ‘Oh, my gosh, do you and your fiancée want to go have dinner or something and go hang out?’” Oliva told HuffPo in 2015. “At first it was cool, and then I kept going up to him at the wedding like, ‘So, you having fun?’ I was just so obsessed with hanging out with and talking with him.” She said she emailed him, but never heard back. “I might’ve got the wrong email… probably,” she added. “That’s what I tell myself.”

In December 2020, John checked himself into rehab for substance use disorder. The comedian has long been vocal about his struggles with drug and alcohol addiction, telling Esquire in 2019: “I drank for attention. I was really outgoing, and then at 12, I wasn’t. I didn’t know how to act. And then I was drinking, and I was hilarious again.” While he was completing the 60-day stint, Olivia tweeted a message of support, writing, “Sending SO MUCH love and support to John Mulaney. You got this.”

2021: Olivia & John Are Dating

A few days after it was announced John and Anna Marie had broken up, reports confirmed he and Olivia were a love match. While the news brought a mix of responses, Olivia said she wouldn’t address the speculative chatter.  In an interview with the Los Angeles Times in November of that year, Olivia said she avoided criticisms so not to “feed into a narrative that’s just not true.”

“It’s definitely not foreign for me to have people speculate incorrectly about things and to have rumors run rampant in one way,” she said. “They 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.” She added, “For whatever reason, it’s easier to blame me. If I try to say anything, I run the risk of being called messy or not telling the truth.”
