Keira Knightley Has Gotten Mistaken for Britney Spears Before!

Keira Knightley changes into a new dress to attend the after party for her movie Begin Again on Wednesday evening (June 25) at the Bowery Hotel in New York City.
The 29-year-old actress recently talked about the celebrities that she has been mistaken for, which include Natalie Portman, Kate Winslet, and one that you probably wouldn’t have guessed.
“But the one that’s surprising is Britney Spears,” she said on The Graham Norton Show. “I get quite excited because I quite like the idea that I could do like that [mimes shimmying], which I can’t do. So I’ve been Britney Spears like three times.”
