Naomi Campbell and Robbie Williams enjoyed a secret year-long affair behind her boyfriend`s back.

The stunning supermodel was dating Formula One boss Flavio Briatore when she began the steamy romance with the pop heartthrob Robbie Williams.

The pair first got together in 2001 after Naomi`s battle with drugs hit the headlines and Robbie was the first to comfort her with a 48-hour romp.

"I walked into Naomi`s bedroom and found them cuddled up in her bed. It was the apartment Naomi shared with Flavio with whom she was supposed to be having a serious relationship. But Naomi didn`t try to hide the fact that she was cheating on Flavio with Robbie", - said Naomi`s friend.

Naomi became obsessed with Robbie and she did all the running around during their 12-month fling.

Their affair ended later that year after a final night of passion at one Naomi`s hotel suites.

A spokesman for Robbie refused to comment on the story.
