Kelly Brook has learnt how to ''use'' sex in her 30s.

The glamour model - who turned 34 in November - insisted she isn't bothered about aging, explaining she finds it ''nice'' showing off her body and ''expressing'' herself as she gets older.

She told Cosmopolitan magazine: ''I don't worry about getting older: it's exciting to find new ways to express yourself. It's nice to be 34, on the cover of a magazine talking about your body.

''I've found, when you get into your 30s, you relax a bit. It's not all about going to the gym or doing yoga everyday or living off green juice.

''You start enjoying life, sex and your body - and you know how to use it. Once you do that, that's when people are drawn to you. That's the most attractive thing.''

The stunning star also discussed controlling her weight, admitting she would rather feel ''fresh'' and have ''rolls'' than make herself miserable by forcing herself to be too slim.

She said: ''I'm not a super-skinny girl and I do love food. For me it's not about doing 1,000 sit-ups before a photoshoot; it's about feeling fresh,'' she said.

''I've got rolls and boobs and I don't ever want to change. I love nights out with my girlfriends: nice food with wine or cocktails.

''I don't do it every day but I don't deny myself either. I love burgers and restaurants where you get hot dogs and champagne!''
