Cheryl Cole doesn't understand why people have cosmetic surgery.

The British beauty has recently relocated to Los Angeles to work on the US version of 'The X Factor' and is astonished by how many people have gone under the knife and lost their "unique" look.

She said: "Everything in the US is a little larger than life.

"I've already seen a few funny sights. I can't quite get my head around everyone having the same nose, because I think it's the unique things about your face that make you beautiful.

"I'm not judging, but unless something is really getting you down, it's best not to mess with nature."

The 'Parachute' hitmaker's new job in the US means she is travelling more, so she is planning to take extra precautions to look after her skin.

She explained to Grazia magazine: "I used to sit on a plane with all my make-up on the whole way, but now I realise I can't do this if I'm flying so much. It's so bad for your skin.

"Now, I'll smother on oil or serum once I'm on board. Actually, I'm going to ask the air hostesses what they use, they must know a few tricks to stop the flying from messing with your skin."
