After four years of marriage, rumours are mounting that Kate Moss and her husband Jamie Hince are on the verge of divorce and sources are suggesting his friendship with another woman could be to blame.

The Sun reports that the supermodel and her rocker husband are allegedly "past the point of no return" and are considering releasing a statement announcing their split.

A source told the publication: "They are properly over as a married couple. It's gone past the point of no return.

"Jamie's just waiting for Kate to move forward with divorce proceedings."

The insider alleges that Moss, 41, grew jealous of Hince's friendship with model Lady Mary Charteris, who is married to rock singer Robbie Furze.

However, Hince, 46, has reportedly insisted that he is just friends with Charteris and has been using the model and her husband as a support system.

The source said: "Mary and Robbie have very much been looking after Jamie through this really difficult time.

"They've been very true and loyal friends regardless of what Kate might think of them."
