Keira Knightley Shares the Worst Part of Her Oscars Nomination

— -- It's safe to assume that Keira Knightley is excited to be nominated for the Oscars.

However, she joked, her pregnancy is putting a damper on her ability to celebrate.

"I can't drink! I'm up for an Oscar and I can't drink at the Oscars!" she told Ellen DeGeneres. "[My doctor] was like, 'Any questions?' and I was like, 'Yes! When can I drink, please?!' I just want a margarita."

Knightley, 29, is expecting her first child with her husband James Righton. Righton, she said, has been doing his fair share of partying for her.

"I'm eating for two and he's drinking for two. It's brilliant," she said. "He thinks that because I'm not drinking the free champagne, he has to. All of it."

The Oscar nominee said she doesn't know the gender of the baby, nor does she have a birth plan.

"What is the plan, apart but to get it out?" she asked. "There isn't the option to keep it in!"
