Brook, 32, who is currently dating former rugby player Thom Evans, said she can't see the point of staying with someone for the sake of it and would rather be single, Femalefirst reported.

"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," she said.

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