Singer Robbie Williams has said he would go gay for actor Brad Pitt, but other men would need to pay 2 million British pounds to bed him, UK's The Daily Mirror reported.

During a two-hour chat with close friends and wife Ayda Field broadcast on the Internet, Williams, 37, half-jokingly asked: “I've got a controversial question. How much would it cost for you to sleep with a man? It's got to be your minimum if a man comes to you and says name your figure.”

Williams undercut his male friends, who mentioned figures of around 5 million pounds, with a 2 million pounds price.

“You never know what could come of this, babe you could be having a new car in the New Year,” wife Field said.

“You never know, let's keep our fingers crossed,” Williams replied. “I'm the cheapest.”

He then went on to state that he would sleep with Brad Pitt for free and was even willing to pay him.

“Brad can negotiate. It's 2 million pounds for Santa, but it's a freebie for Brad Pitt,” he said, then added with a smile: “How much would I have to pay him?”

Williams' next studio album is set for a fall 2012 release.
