Sarah Harding and her boyfriend Tom Crane each have a celebrity crush they are allowed to have sex with.
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.
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!"
