Suki Waterhouse looks like a ''tramp'' when she's lounging around at home.

The 22-year-old model - who is dating Bradley Cooper - admits she doesn't make an effort to look good when she's at home although she is known as a style icon publicly.

She told LOOK magazine: ''Well, there's my presentable self and my normal self. I'm the laziest person - that's my normal self. When I'm hanging around my house, I literally look like a tramp. I love being comfortable and having no make-up on. As soon as I get into my house I put on sweats and pyjamas. I love fashion and that's where my presentable self comes in. But I need help - if I didn't have a stylist and make-up artist, I'd look like s**t.''

Suki goes through phases where she switches her look and admits she recently donned a 90s art teacher look with bright colours and patterns, but currently prefers ''biker chic''.

She said: ''It [my style] changes constantly with what I buy and new things I have. I went through a phase about a month ago of dressing like a 90s art teacher, kind of Drew Barrymore.

''[At the moment] I got loads of leather trousers form Burberry so I'm quite into biker chic with flats. I've got Jimmy Choo flats and a thick Mulberry sheepskin jacket. I also just got some wicked new Christopher Kane stuff. I'm quite into crop tops at the moment too.''
