Kate Moss is reportedly planning to marry Pete Doherty after he bought her a diamond engagement ring.

Kate, who was wearing the huge vintage diamond ring and Pete, were seen kissing on Friday (8/11) at the recording of British music TV show ‘Transmission’.

Friends of the supermodel have revealed the ring was a present given to her by junkie rocker Doherty last week.

They also said that when Kate attended Primal Scream singer Bobby Gillespie’s wedding two weeks ago she told them: “It’s going to be me next.”

On Friday, the happy couple left the TV studio together and spent the night at the home of Kate’s actress friend Davinia Taylor.

A friend of Kate’s is quoted by Britain’s Daily Mail newspaper as saying: “Even when she was supposed to be with Russell Brand she was still secretly seeing Pete. He is like an addiction that she can’t cure.”

Doherty recently attended a Portuguese rehab clinic to try to kick his crack and heroin addiction again.

On entering the clinic the Babyshambles singer pledged he would marry Kate once he was clean.

The couple first got together at Kate’s 31st birthday in January last year, but split a few months later after the model was photographed snorting cocaine.

This week Kate plans to fly to Ibiza with Doherty, where Babyshambles will perform at the annual Ibiza Rocks event.

It is rumoured that the model’s friend Jade Jagger plans to throw an engagement party for them on the idyllic island.
