"I remember suspecting an ex of cheating on me," she revealed. "I woke him up in the middle of the night and I was like, 'Are you fucking so-and-so?'"
"And he was like, 'You're crazy.'"
Anna says she decided to trust him, despite a "gut feeling" telling her otherwise:
Of course I don't want to believe that anything [is going on]. But there was that gut feeling that was starting to grow more and more.
Unfortunately, she didn't get confirmation of the cheating until after they split, when some mutual friends told her the truth.
And Anna said it was a fear of seeming "crazy" that stopped her from trusting her gut in the first place:
I do think as women we're sort of taught to suppress fear or suspicion because we might be deemed as suspicious or neurotic or crazy or whatever. So I think that in my case I was like, "OK, maybe he's right. Maybe I am crazy."
Anna is currently dating — and possibly engaged to — cinematographer Michael Barrett, but she's had some high-profile relationships in the past. From 2004 to 2008, she was married to actor Ben Indra.
And, of course, she was famously married to Chris Pratt from 2009 to 2017.
They announced their split in August 2017, and fans were caught very much off guard by the news.
