Keira Knightley Works Big Baby Bump on the Red Carpet in Feminine Dress: See Her Glam Maternity Style!

There's that bump!

Though Keira Knightley admitted that she's been avoiding body-conscious looks while pregnant, she can't hide that baby bump anymore! The Imitation Game actress attended a private reception for her Oscar-nominated film on Thursday, Feb. 5, in London, and even in a loose floral dress, her bloomed bump popped right through.

Mrs. James Righton, 29, donned a custom dress by Michael Van Der Ham—a feminine design just roomy enough to partially disguise a bump while standing.

But once she took the stage for the pre-BAFTA chat, Knightley, who also sported Tabitha Simmons shoes and Aurelie Bidermann earrings, rearranged her frock around her frame, which revealed her enlarged tummy—and just how close she is to welcoming her first child.

Joining her on the scene: her dapper Imitation Game costar, Benedict Cumberbatch, who is also nominated for his role in their WWII-set film.

While Knightley has been a fan favorite since her Pirates of the Caribbean days, she admitted that on this press tour, it's been all about relinquishing the limelight to Cumberbatch, thanks to his extremely devoted fan base.

"I actually had a really embarrassing moment at the London premiere, because [his fans] scream more than I've ever heard for anyone else, but I had a publicist with me and she went, 'You know, go sign some autographs,'" Knightley told Seth Meyers on Late Night last November. "I went over there and went 'Oh yeah, of course, of course, no problem!' And they were like, 'Oh no, we don't want you. We're just here for Ben!'"
