Keira Knightley: My ‘Waist Has Disappeared’

01/25/2015 at 07:30 PM ET

Pretty in purple!

Mom-to-be Keira Knightley kept her bump under wraps in an Erdem gown while on the red carpet at Sunday’s Screen Actors Guild Awards.

The actress, who is expecting her first child with husband James Righton, has been opting for flowing frocks during this year’s awards season — and it paid off!

“It’s boiling out here,” she told E! News. “It just means you’re not going to wear anything tight. Some people do wear tight things … I don’t want to go for that. It’s all just quite loose.”

Knightley, who joked her “waist has disappeared,” added, “I’m quite comfortable. The shoes are quite high — they may come off later! I can [say], ‘Well, I’m pregnant so my shoes have to come off,’ and nobody is allowed to say anything so that is nice.”

Despite previously admitting to keeping snacks in her clutch, Knightley joked she was still starving. “I keep eating my hair. I’m fairly hungry,” she said.

Knightley, 29, is up for outstanding performance by a female actor in a supporting role for The Imitation Game, which is nominated for a total of three awards.

I don’t know why I have a feeling she’s having a boy, but I do. I also have a hunch that they’ll use James for either the first or middle name. Of course, now that I’ve said all that, she’ll probably have a girl! 😉
