(Cover) - EN Star Style - Alexa Chung doesnt run to keep fit because it makes her look like an idiot.

The TV star is famed for her willowy physique and quirky sense of style. Alexa used to be a model, and says her slim body is just her natural shape. She knows she should be dedicated to exercise to be healthy, but she just doesnt find it that exciting.

I walk a lot, but I dont run. I try not to run simply because I look like an idiot, she said. No, I dont do any formal type of exercise which is quite bad isnt it? I should condone healthy living. I have to walk around quite a bit, though, cos sometimes I get too hyper.

Alexa doesnt worry about her appearance, and isnt stressed about getting older. She is 27 and hopes she never succumbs to the lure of the surgeons knife, but knows it might happen.

I dont think Ill have any work done, she told Company magazine. I can totally tell when somebody has had stuff done. You just look weirder. But, you know, interview me in 20 years time and maybe Ill have a frozen face! (C) Cover Media
