Kelly Brook would never stay in an unhappy relationship.

The model-and-actress - who is currently dating former rugby player Thom Evans - says she can't see the point of staying with someone for the sake of it and would rather be single.

She said: "I've been through some big break-ups and although it's hard to do, I'm never one to just go along for the convenience of it, so I'll always follow my instincts. If you're not completely happy in a relationship, I think you've just got to know that if you're feeling like things aren't going right, then just have the faith that maybe you both deserve better. Don't live in fear of losing someone."

Kelly - who has previously dated Jason Statham, Billy Zane and Danny Cipriani - also insisted she doesn't like dating famous men because she thinks their egos are too big.

She told Britain's Glamour magazine: "My relationships are only high-profile I guess because people outside my house see them coming in, but I don't really go out with famous guys.

"Billy was the only person who was kind of known a little bit. When I was with Jason he was a high-board diver, he wasn't famous. I've just got good taste - now, he's a Hollywood movie star. Once they become famous, they develop this thing called ego and it's a bit of a turn-off. Then I send them on their way!"
