Robbie Williams has one complaint about the groupies he picks up, they all want to marry him.

The singer is single and determined to enjoy his bachelor lifestyle for a few more years - but the girls he takes back to his Los Angeles mansion for one-night stands are no longer just after sex.

Williams, 31, says, "Think about it, there's a lot riding on sleeping with Robbie Williams these days.

"They look at the staircase and the Andy Warhol originals and the fact that I have a chef, and they think that if they don't sleep with me immediately I will respect them more, and if I do respect them more then it could lead to relationship, marriage, kids, the lot.

"Trust me, that can be very frustrating, especially if all I am up for is a bit of meaningless sex."
