Josh Hartnett, Tamsin Egerton expecting second child

Feb. 28 (UPI) -- Josh Hartnett and girlfriend Tamsin Egerton are expecting baby No. 2.

Egerton, a 28-year-old English actress known for the Starz series Camelot, confirmed she's expecting again with the 38-year-old American actor by debuting her baby bump Sunday at the Vanity Fair Oscar party.

"This is not feeding the baby nourishment," she joked to People while snacking on beignets.

Egerton showed off her growing belly in a form-fitting black dress next to Hartnett, who wore a black tuxedo. She reposted a picture on Instagram of herself with Harnett and model Helena Christensen at the bash.

"Repost @helenachristensen #vanityfair," the star captioned the snapshot.

Hartnett and Egerton started dating in 2012 after meeting on the set of The Lovers. The couple welcomed their first child, a daughter whose name they have yet to announce, in November 2015.

"She's five months old. She's the apple of my eye. She's perfect in every way," the actor gushed on Live! with Kelly and Michael in April 2016.

"It puts things in a totally new perspective. Your ego kind of just melts away when you have a new kid. Your heart kind of leaves your body," he said. "It's really terrifying, but it's beautiful. I love it more than anything. I wish I would have started it earlier."

Hartnett is known for playing Ethan Chandler on the Showtime series Penny Dreadful, and will star in Valley of the Gods with John Malkovich. Egerton portrayed Guinevere on Camelot, and last appeared in the movie The Brothers Grimsby.
