An apparent home-video of supermodel Kate Moss and her boyfriend Pete Doherty has been leaked on to the web.The grainy three-minute clip gives a behind the scenes snapshot of the couple's private life and has received more than 31,000 hits on home video haven, YouTube.Babyshambles frontman Pete is seen strumming a guitar for the camera while singing a song.Moss enters the room, scantily clad in a see-through nightie and sits in a chair, kicking her legs to the music and joining in by adding a few choice swear words to the little ditty.As Doherty sings about an oak tree, Moss cries: "What oak tree? You're such a liar, such a liar. And a fantasist."And when he trills "la, la, la..." she orders him: "Don't la la me."The footage is headed "KP Nuts" and subtitled "Peter Doherty performing new song KP Nuts with Kate Moss".A spokesman for Babyshambles' record company, Parlophone, said he had no idea how the clip had ended up on YouTube.© Independent Television News Limited 2007.
