British pop star Robbie Williams refuses to have sex in his own house after fearing it may become "contaminated".

The ANGELS hitmaker - who has previously romanced ex-ALL SAINTS star Nicole Appleton and supermodels Rachel Hunter and NAOMI CAMPBELL - never invites a girl back to his Los Angeles home in case their bedroom antics irreparably alter the room's karma for him.

The 31-year-old admits, "I didn't have sex in for a long, long time. In my house in Los Angeles it has never been important to me.

"I love my room and my bedroom and don't want to have anyone back there.

"When I travel I go to the other extreme. I offer myself far and wide to all the known universe."
