We’re absolutely obsessed with Anne Hathaway’s performance in HBO Max’s The Witches.

Turns out, the actress was pregnant with her son Jack while filming the movie! Anne herself confirmed it while appearing on Monday’s episode of Live with Kelly and Ryan.

“Now I have a beautiful almost-11-month-old boy, but I was pregnant when I made The Witches, so technically he’s all over that performance,” she joked.

She also recalled an early snafu while getting costumed for the film.

“She goes, ‘I really want you to have a really tight waist.’ And I had just found out that I was pregnant and I was like, ‘Mmm, no. No, I don’t think so. No,'” she said. “And she was like, ‘Well, why?’ And I was like, ‘Eh, you know, I just know myself.’ I’m scrambling for a reason.”

She continued, “And I’m like, ‘I just know myself and I know that I won’t be as free. I won’t be as free if I’m constrained around my middle, so we just better make everything very loose.'”

Haha! Well, eventually everyone figured it out, right? Watch the full clip above.
