Julia Stiles shows off baby bump in Instagram selfie

We knew that Julia Stiles is pregnant.

But what we didn't know is what she looked like with a baby bump. Well, that's all over now — Stiles decided to show off her impending arrival by featuring her baby bump in an Instagram selfie. The caption? "Alright, I couldn't resist."

Alright, I couldn't resist.

We love it, particularly seeing mom's bemused look.

Stiles, who's been starring in the British "Riviera" limited series, has been engaged to actor/cameraman Preston J. Cook since 2015; she showed off the ring in January 2016, also on Instagram.

Best Christmas Ever! 💖
