They have only just celebrated their four-year wedding anniversary, but it seems that Kate Moss and Jamie Hince's marriage may be on the rocks.

According to insiders, the rock'n'roll couple are living separate lives and have not spoken since they had a blazing row at their North London home a few weeks ago.

The Sun's Michael Hamilton reports that pals are growing increasingly concerned for the supermodel and The Kills guitarist, who have not been pictured together since 10 April.

"There have been arguments and jealousy, although nothing is going on with either of them," a source said. "They both seem interested in different things.

"There was a blazing row. Jamie has been saying he's worried he has wasted the last eight years."

The Sun also reported that Hince's friendship with fellow musician and model, Lady Mary Charteris, is another source of contention

"Kate does not like Mary at all and the feeling is mutual. When they have met at functions, Mary has called her 'Croydon Kate' to her face," the insider claimed.

To add fuel to the fire Hince was seen at this year's Glastonbury Festival on his own, having previously attempted the event with his other half.

Moss, meanwhile has been spotted on several trips, including travelling to Paris for Haute Courture Fashion Week, sans Hince.

Moss married Hince on 1 July 2011 at St Peter's Church, Southrop, Gloucestershire. For her big day she wore a dress by John Galliano.

IBTimes UK has contacted Moss and Hince for comment and is awaiting reply.

Hince is expected to embark on a US tour with his band later in July.
