Hollywood star Keira Knightley feels trapped in a gilded cage surrounded by unwanted media publicity - but accepts the paparazzi are only doing their job.

The 20-year-old Pirates Of The Caribbean beauty tries her best to shun pesky photographers, but appreciates it comes hand-in-hand with Hollywood success.

She says, "I accept the paparazzi part of being famous, though - after all, this is business about putting audiences into cinemas.

"But it can be very hard when you're a woman, on your own, facing that sort of attention.

"It's like being in a cage at times - even if it is gilded one."
