Robbie Williams treated a fan to a special performance on the social networking website Chat Roulette.
The Rock DJ singer gave a surprise preview to Adam Houabi when he sang new material to the 19 year old through video chat.
Essex lad Houabi got the shock of his life when Robbie appeared on his laptop screen, according to 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 would be out in October.”
Houabi filmed the personal serenade and posted it to Youtube but a spokesperson for Robbie denied that the featured song would be on his highly anticipated new album which is due to be released later this year.
The singer’s wife Ayda is due to give birth in August.
