What Knightley really needs is a Carribean cruise

She's only 21 years old, but Keira hasn't taken a holiday for the last few years

She's only 21, but Hollywood star Knightley says she needs to take some time off.

"It's my instinct to think I have to say yes or there won't be another job. But I've been working on films and i need a break," said The Pirates of the Caribbean actress.

"I think I just need to take time out to get a bit more of my own life back," she added.

"If that means I have to go to the back of the queue as far as acting is concerned, then I just have to accept that," the actress said.

The Bend It Like Beckham beauty says of her looks: "I do think I must have a nice face because I'm completely aware my face gets me work.

But the problem is that If you happen to be someone who people think of as pretty, you also get so many people whose business it is to comment on your looks.

"I've been to photo shoots where the photographer has told me he'd kept my legs out of the shot so I don't need to worry about them - that of course makes you worry."

Then I've had make-up artists who've told me they need to shade the top of my nose so it won't look so broken. I also got rejected for a job once because someone said I had a funny mouth. "They are all things you start focus on.

You start off thinking you're okay, Then you have to go to some event and you remember you have a weird mouth, a broken nose and horrible legs," www.Hollywood.tv quoted the actress as saying. Keira said her father, actor will Knightley, used to work as a taxi driver to make ends meet.
