Pete dedicates song to 'fiancee' Kate

Singer Pete Doherty described supermodel Kate Moss as his fiancee as he dedicated a song to her during a gig last night.

Moss appeared on stage alongside the Babyshambles frontman as he performed a solo gig at the Hackney Empire in east London.

As he introduced the track KP Nuts, he said: "I am dedicating this song..." before the crowds interrupted him to shout "Kate, Kate". The singer then replied: "Yes, to my fiancee."

Moss then appeared on stage to sing a chorus after she reportedly flew in from Los Angeles especially for the show.

The impromptu double act came during An Evening with Peter Doherty, billed as a show including "poetry, readings and acoustic songs" and some "very special guests".

Moss was wearing a ring on her engagement finger as she performed briefly alongside her boyfriend, who was wearing a grey suit, colourful necklaces and his trademark hat.

An apparent home video of the song, featuring the pair, has already become a hit on the internet after it was posted on YouTube.

Doherty is seen strumming a guitar for the camera while warbling a song as Moss enters the room in a see-through dress with only a pair of knickers underneath.

Throughout the track she swings in a 70s-style chair suspended from the ceiling and kicks her legs to the music.

At one point she interrupts, saying: "Sonny and Cher we're not". YouTube has already recorded some 31,000 hits for the three-minute clip.
