Keira Knightley was recently rushing through the airport when a fan asked her for an autograph -- thinking she was someone else.
"Actually I think I have to apologize to Anne Hathaway because the woman (at the airport) thought I was being really rude as Anne Hathaway not giving her a picture as Anne Hathaway, but I was really only saying that I promised I wasn’t Anne Hathaway — which I am not."
Knightley confessed that it's not the first time she's been mistaken for another actress.
While she is most certainly not Hathaway, Knightley, 29, did recently take the Oscar winner's place in this year's "Laggies," the follow-up to director Lynn Shelton's "Your Sister’s Sister."
"She dropped out very late in the process and they were scrambling a bit to find somebody and I was...well, I didn’t have anything," Knightley admitted. "Stylistically, it’s completely different from what I had been doing previously so it was very much 'jump in and hope for the best.'"
Knightley was recently nominated for a Screen Actors Guild award and Golden Globe for her role in "The Imitation Game."
