KEIRA KNIGHTLEY - KNIGHTLEY: I'M NATURAL

Rising teen star KEIRA KNIGHTLEY has slammed rumours she "admitted" to having cosmetic surgery.

The PIRATES OF THE CARIBBEAN: THE CURSE OF THE BLACK PEARL actress was reported to have had collagen injections in her lips and Botox, and was quoted as saying, "Yep, I've had my lip done."

But the angry 19-year-old fumes, "I've been reading some quote that's apparently from me admitting to having had my top lip done and Botox.

"It's ridiculous. Actually, I might have shot myself in the foot with that as I heard the story about my lips and I went to a party and somebody asked me about that and I went, sarcastically, 'Oh yeah, I've had my lips done,' which was stupid of me."
