This is the first marriage for Munn and the second for Mulaney. In May 2021, the "Everybody's in LA" host was reported to have split from his wife Anna Marie Tendler after six years of marriage. They finalized the divorce the following year.

In September 2021, Mulaney revealed on "Late Night with Seth Meyers" that he and Munn were expecting a baby. He also shared details about the timeline of their whirlwind romance, explaining that after getting out of rehab in February, he went to Los Angeles and began dating Munn. They first met at Meyers' 2013 wedding.

"She got to date me right out of recovery, which is what they call a reverse catch," he quipped.

"I was starstruck when I met him," he said. "I went, 'Oh there you are. You're that thing I couldn't find.' I was looking in not good places."
