JACK OSBOURNE is laughing off claims he's romancing model KATE MOSS, insisting he's only trying to be a good friend to someone in need.

Osbourne celebrated Moss' birthday with the British beauty last month after she underwent a stint in rehab to kick her cocaine abuse.

Osbourne, who has also dealt with drug dependency issues in rehab, insists, "I've known Kate for a few years and I went out with her for her birthday. I don't push help on anyone - if she feels that she needs to call me, whatever."

Don't worry about denying the rumour boy, nobody took it ever remotely seriously anyway.
Well, actually Kate Moss dated Pete Doherty, and after that I guess everything else is possible...
