Robbie Williams may be happily married to wife Ayda Field, but there is one person he would still want to sleep with if the opportunity arose. 

The Take That star admitted during his Rudebox radio show that it would take a vast sum of money for him to bed a man, although there's one male celebrity he would seduce for free:

"It's £2million for Santa, but it's a freebie for Brad Pitt!"

Along with this juicy confession, Williams also revealed that during his days as a single man about town he also had his eye on two other well-known personalities:

"Is there anyone in the room who wouldn't sleep with Carol Vorderman?', he asked before telling listeners that singer Lulu was also the object of his affection earlier on in his career. "If it came my way, I would have gone that way. I definitely would."
