Let me entertain you ... on Chatroulette! Robbie Williams serenades fan on internet site

Robbie Williams surprised a male fan with a solo performance over an internet video chat site.

The 38-year-old singer appeared on Chatroulette - where random users are video linked to each other - to serenade 19-year-old Adam Houabi, an accountancy student from Essex.

Houabi told The Sun: "One minute I was talking to a bloke from Algeria ... then amazingly Robbie appeared.

"I didn't believe it was really him so he pulled his shirt down to reveal his chest tattoos and showed me five cameramen round him in his Hollywood studio.

"Then Robbie told me he was recording a new song and started singing. He said it was called 'Losers' and it would be out in October.

"It was good. I liked it. I've chatted to a few strange people on Chatroulette before but never a superstar!"

A spokesperson for the singer denied the song will be his comeback single.

Robbie recently had to pull out of performing at the Olympic Games closing ceremony because the date clashes with the impending birth of his first daughter with wife Ayda Field.

A source said: "Robbie had been lined up to perform solo material and it was hoped he would sing with Take That.

"It meant organisers had to adjust the entire schedule because Robbie is an extremely high-profile performer and had been given such an important role in the finale.

"Obviously Robbie has to put his family commitments first. It's just a shame he didn't realise earlier."
