Pop hunk Robbie Williams got a shock after he heard Sharon Osbourne speaking dirty down the phone to him - until he realised the matriarch thought she was chatting to husband Ozzy.

The former TAKE THAT star swapped numbers with wild rocker Ozzy after a successful first meeting and was horrified when he answered his mobile phone in a Los Angeles hotel to hear Sharon purring down the line - which has been revealed in Williams' forthcoming autobiography FEEL.

The book claims Sharon rang Williams asking, "Are you naked?" to which a bewildered Williams replied, "Yes".

Sharon then declared, "I'm coming up," to which Williams admitted, "Sharon it's Robbie Williams."
