Emma Watson worries about her looks.

The 21-year-old beauty - who has modelled for Burberry and is an ambassador for cosmetics company Lancome - finds the pressure to look good in Hollywood overwhelming but says she is determined not to conform.

Emma said: "I do worry about the expectation to look a certain way. I find LA quite scary because of that - all those young people having plastic surgery. But the thing is, I don't want to look like everyone else.

"I don't have perfect teeth, I'm not stick thin. I want to be the person who feels great in her body and can say that she loves it and doesn't want to change anything.

"It's ridiculous that seems such an unrealistic goal. I think the actresses who are really successful are the ones who are comfortable in their own Skins and still look human."

Despite her worry over her looks, Emma loves to relax with her friends and says she can hold her own when it comes to drinking alcohol.

In an interview with the UK edition of Elle magazine, she explained: "I love dancing. You'll always get me up on the dancefloor. I'm not that much of a lightweight. My dad's great hobby is wine, so it's always been part of our family life. For someone so little I don't get drunk very easily. It's quite a good talent, I'm not challenging anyone to a competition though."
