Cameron Diaz says her biggest weaknesses are burgers and fries. The 'What Happens in Vegas' actress admits she can't resist the greasy treats.

She said: "I eat healthily but love my burgers, and if you put a bowl of fries near me, then it's over. Normally, though, I'll have a half-order of something and save the leftovers. I'm queen of leftovers." Cameron also attributes her active, healthy lifestyle to keeping her sane, adding to Britain's Shape magazine: "I hike, snowboard and surf. I admit I do hire a personal trainer as well, but for me working out is a big part of keeping mind and body together."

The 35-year-old actress recently admitted she had altered her eating habits because she was gaining weight as she got older. She said: "I used to be able to eat and drink anything I wanted - fried chicken, onion rings, half a bottle of wine - then go right to bed. But as you get older your insides rebel against you!"
