Irina Shayk doesn't ''believe in plastic surgery''.

The 29-year-old model - who is rumoured to be dating actor Bradley Cooper - claims cosmetic procedures aren't necessary and simply believes being confident can help women to ''feel special'' at any size.

She said: ''I don't believe in plastic surgery. I believe women have to love their bodies, and that it's all about confidence. When I do shoots, I say to myself, I love my body and I'm not afraid to show it. I hope every woman will feel special and be in love with her body, whatever her size.''

Instead, the brunette beauty spends a lot of time working out and enjoys changing up her exercise routine to ensure she doesn't get bored.

She explained: ''To get into lingerie or a swimsuit for a shoot you have to feel your best, and of course you have to train. Lately I've taken up ju-jitsu, which is great fun and also great cardio. You have to find something that works for your body. I get bored very easily, so I'm always trying to find something different.''

Irina also shared the secret behind her flawless sense of style and chooses to invest in ''classic pieces'' instead of buying into trends.

She told the Daily Telegraph newspaper: ''I've been pretty smart with my money. I hate to waste money on clothes. I prefer to buy classic pieces that you can have in your closet for years.

''My style is very simple; I try to be low-key. I can spend my day in sweat pants or gym clothes. When I'm not working I don't like to dress up; I hate [doing my] hair and make-up - it's kind of boring.''
