Keira Knightley took to the red carpet to debut her new Star Trek inspired do.

Sporting an over-the-top dress to match her out-of-this world do, Keira looked glum (see pictures here) as she posed for the hoard of paparazzi that gathered to catch a glimpse of a usually flawless Knightley at the Los Angeles premiere of her new film, Atonement.



The 22-year-old told US chat show host Ellen DeGeneres yesterday that she is quickly becoming known for her willingness to bare all in films.

She said: "I don't know why it happened this way. People ask me to pose naked and I just say yes! I find it vaguely liberating,

"I hope I don't become a nudist, but I'm definitely on my way!"
