Get ready to welcome another baby to Hollywood! Josh Hartnett (whom you might recall from films such as Pearl Harbor, Black Hawn Down, and, more recently, Oh Lucy!) and wife Tamsin Egerton were one of the celebrity couples in attendance at the Vanity Fair Oscars after-party (see all the hottest dresses here), and in addition to all the baby bumps we expected to see (Ciara, Rosie Huntington-Whitely), Egerton surprised us all by adding her own to the mix!

The couple, who already share a little girl together, posed for photos in which Egerton鈥檚 very visible bump could be seen peeking out from beneath her elegant black gown. As the evening got underway, Egerton had her fill of beignets, joking to People, 鈥淭his is not feeding the baby nourishment.鈥

Hartnett, who just so happens to be a softie when it comes to his daughter (鈥渟he鈥檚 the apple of my eye, she鈥檚 perfect in every way,鈥 he previously gushed on LIVE with Kelly), is surely over the moon. these two.

Also in attendance that evening? Hartnett鈥檚 ex-girlfriend Helena Christensen, who he split from back in 鈥08. But don鈥檛 worry: There鈥檚 no bad blood between these three. The supermodel took to social media to share a shot of her alongside the happily expectant twosome, saying, 鈥淰anity鈥ove these two.鈥

Congratulations, guys!
