Kate Moss gives Pete's home video the X factor

As he strums a guitar in front of the camera, a halfnaked Kate yells at him: "Rot in jail you c***! Rot, rot, rot, rot, rot, rot."

The weird footage was shot by the Babyshambles frontman at Kate's cottage in the Cotswolds.

No Sonny and Cher: While Pete Doherty plays his new song KP nuts, a halfnaked Kate Moss enters the room

It shows Pete filming himself sitting in a room playing one of his new songs, while a scantily clad Kate - seemingly a little worse for wear - cavorts in a chair next to him.

She randomly interrupts his singing by either joining in or hurling obscenities at him.

Swinging her legs and puffing on a cigarette, she begins by whistling along to Pete's new tune - KP Nuts, a reference to their first names, Kate and Pete.

WARNING: Video contains strong language

The song is actually quite sweet and melodic, so it's a shock to hear Kate cutting in with some foul outbursts.

As he sings sweetly, "you're giving all your precious love to someone that I... I just couldn't find", Kate chips in with: "Rot in jail you c***!"

The video posted on YouTube was filmed during one of the couple's trips to Kate's Cotswold cottage

She then kicks out at him, nearly knocking him off his chair. Then, singing along with him, she jokes: "Sonny and Cher we're not."

The pair then have a bizarre exchange over one of his lyrics, when he sings: "Underneath the oak tree."

Kate then replies: "What oak tree?"

"The oak tree," says Pete.

To which she cries: "You're such a liar, such a liar. And a fantasist."

Pete then begins to sing the "la la la" section of the song, which prompts the woozy Kate to say "Don't la la me".

Kate Moss swears and yells at her boyfriend and at one point nearly knocks him off the chair

She disappears to "get a drink" but then reappears at the doorway and yells: "Oi c***face!"

The video was posted by Pete onto a fan website, before someone else put it on YouTube.
