Thankfully it didn't happen to Wilson quite in that way.
"No, no no, it didn't, that part's made up. I said all those things about those people, but they didn't hear it," she jokes.
There are plenty of other anecdotes from their life that have been exaggerated for the show.
"When we moved in together, I was a little claustrophobic, going from living alone to sharing your space, and so in the show David wrote about how my character starts hiding out in her car, watching TV shows on her iPad in there, ordering food to her car, putting up curtains, having friends visit her in there, and throwing a party. So it's obviously a bit more heightened and ridiculous than real life, but at the same time, our stories are the kernels."
Indeed, while Jake and Annie are the centre of the show, like any good sitcom, the surrounding ensemble are equally important, and they too are inspired by people in Wilson's life - in the show Annie has two gay dads, both named Kevin, inspired by two of Wilson's gay friends who are both called Kevin, and also her own father.
"He's not gay but is always in competition with me, it seems - when I got engaged in real life, he got engaged right after us, and we had a bit of a Bride Wars type scenario ... On the show, the Kevins get engaged after us, and there's a bride war, but when my real dad saw the show, he loved it, and had no idea it was based on him."
So while the couple are definitely having fun, sending themselves up in the series, Wilson feels plenty of empathy for Annie.
"I do definitely have an anger streak, but I always say, well it's because I'm Italian, or it's because I'm a Scorpio, and my husband just says, 'Actually, you're an actress'," she laughs. "For my husband, who is very laid back and always in a nice mood, I think it's been startling for him to live with someone who's so volatile. And that's really where the inspiration came from."
