Robbie and Naomi had secret romance

British pop star Robbie Williams secretly enjoyed a raunchy year-long affair with Naomi Campbell in 2001 - even though the model was in a serious relationship with racing mogul Flavio Briatore.

Campbell's former personal assistant Rebecca White claims she accidentally caught the pair in the throes of passion in the catwalk queen's London flat.

But far from being embarrassed, they simply ordered her to arrange snacks to keep their energy levels up.

White tells the News Of The World: "The first time I actually met him was that day in February 2001 when 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.

"Naomi didn't try to hide that she was cheating on Flavio. I lived in the apartment below and every few hours they would summon me up to bring them food and drink."
