Nicole Kidman has denied reports that there is any romance between her and Robbie Williams - insisting they are just good friends.

The sexy actress met Robbie after he invited her to record a duet of Frank Sinatra's Something Stupid with him, and there have been reports that the two grew to become more than just friends.

But the Moulin Rouge star has dismissed that the two are having an affair - even though she thinks he's irresistible. Nicole explains, "Robbie and I have become good friends - that's all."

And to reports that they recently spent a night together in a London hotel she blushes, "I was in London and we filmed our video together. It's not what people might think, but Robbie is irresistible because he is so much fun to be around. He's a very funny man."
