The `Angels` singer - who is happily married to actress Ayda Field - was asked during a two-hour website how much money he would want to have gay sex and he joked it wouldn`t be as much as everyone thought.

He said during the chat, which took place with close friends and Ayda: "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."

While his friends said payments of around £5million, Robbie interrupted and said: "I`ve thought, I`m coming in, £2million."

When Ayda suggested he had "undercut the competition" he added: "You never know what could come of this, babe you could be having a new car in the New Year.

"You never know, let`s keep our fingers crossed. I`m the cheapest."

However, the Take That star admits he would sleep with Hollywood heartthrob Brad Pitt for free.

He quipped: "Brad can negotiate. It`s £2m for Santa, but it`s a freebie for Brad Pitt. How much would I have to pay him?"

While he joked about sleeping with a man, Robbie, 37, is extremely happy with Ayda and he is determined to be an even better husband to her in 2012.

Speaking on his Radio Rudebox online show, he said: "My resolutions, I want to be a better husband. I want to be a better guy and I want to be as happy as I can be. I also wanna get really fit next year, I have got an album coming out and I want to look the best pop star I can look at that time.

"So there will be OCD running up hills I think. I am going to ask for happiness, that is all you need."
