We'll always have "King Arthur."

Keira Knightley has refused to allow any enhancement of her cleavage on publicity photos for her upcoming movie, "The Duchess," Britain's Daily Mail reports.

Studio heads reportedly want to enlarge Knightley's bosom in the photos, but the actress, 23, put her foot down.

"She has insisted that her figure stay in its natural state," an insider said. "She is proud of her body and doesn't want it altered."

This isn't the first time Knightley has faced this dilemma. The actress drew negative attention in 2004 with her larger-than-usual breasts in publicity stills for "King Arthur."

"Those things certainly weren't mine," Fox News quoted her as saying in 2006. According to Knightley, the studio marketing team was behind her suddenly C-cup breasts, but gave her final approval on the photos.

"I was like, 'OK, fine. I honestly don't give a s---,'" she recalled.

Knightley has expressed dissatisfaction with her small bustline. "I would love to have [breasts]!" she told Britain's GMTV last year, adding, "I'm never going to get [them]. I'm naturally who I am."

While she's a fan of going au naturale in "The Duchess," Knightley looks "flat-chested in the whole movie," the source says.
