Kate Mara is showing off her growing stomach!

On Sunday, the 35-year-old pregnant actress attended Elton John's AIDS Foundation Oscars after-party at West Hollywood Park, alongside her husband, Jamie Bell.

The couple's night out marks their first public appearance since two sources confirmed to ET last month that they're expecting their first child together. Bell, 32, already has a 5-year-old son, Jack, with his ex-wife, Evan Rachel Wood.

Mara was glowing at the event, sporting a short, long sleeve, white Giambattista Valli dress, which she paired with a Tyler Ellis clutch and black Jimmy Choo heels. Her handsome date opted for a classic Dior tux for the occasion.

Mara wasn't the only pregnant celeb to debut her bump at the 2019 Oscars. Prior to the ceremony, Krysten Ritter shocked fans when she showed off a very noticeable bump in her burgundy Reem Acra gown. 

Ritter, 37, was glowing as she posed alongside her longtime boyfriend, Adam Granduciel, while cradling her bump.
