‘I packed a lot into this… Is it September now? I went to rehab in September, I got out in October, I moved out of my home from my ex-wife,’ Mulaney began.

He added that she was also right out of recovery when they started dating, adding she has ‘held my hand through that h**l that was his recovery.’ 

Munn had tweeted out support to Mulaney back in December 2020 in a tweet that read, ‘Sending SO MUCH love and support to John Mulaney. You got this’ with a red heart emoji and a lightning bolt emoji. 

‘I got into this relationship that’s been really beautiful with someone incredible. And we’re having a baby together. I was nervous when I was about to say the news!’ he said.

‘I’m gonna be a dad. I’m… we’re both really, really happy,’ Mulaney added.

Mulaney also asked Meyers, a father of two kids himself, ‘what do you say when you meet them?’

‘Because I don’t want to be too formal, like, “Hi, I’m John,”‘ as Seth joked that being a father would be hard for him, because they, ‘won’t know your work.’ 

‘Will they know me as a writer?’ Mulaney joked, while also asking if they have triplets, ‘can we name the ugliest one Seth?’
