Sarah Harding and her boyfriend Tom Crane have "fantasy sex partners".

The Girls Aloud beauty and her DJ lover are settled in their relationship, but admit they have a rule which allows them to sleep with one Hollywood star each - should the opportunity arise.

She said: "We do have our fantasy sex partners, though - Tom's is Megan Fox, so if he got the chance with her then he'd be excused. And mine is Brad Pitt!"

Tom added: "I should pick someone closer to home, someone I might bump into all the time!"

Sarah and Tom have been dating for three years, and work hard to keep their romance and sex life alive.

She explained: "The key to a good relationship is learning how to keep falling back in love with each other. We try and have a date night once a week. Being at home together we can get on each other's nerves, so it's nice to take ourselves away from all that.

"Things can go stale in a relationship and I think having a couple of romantic days in a hotel can bring the spark back. I'm more into romance than kinky stuff - I'm not into whips and chains!"
