Musical murderer Kate Moss

Kate Moss' relationship with boyfriend Jamie Hince is threatening to wreck his band.The British supermodel has been dating The Kills' guitarist for around a year, and his bandmate Alison Mosshart is reportedly growing increasingly frustrated at the amount of time the pair spend together.Alison often has difficulty contacting Jamie when he is with Kate and is beginning to fear for the future of the band.A source told Britain's The Sun newspaper: "Alison is feeling really isolated at the moment."While she understands Jamie likes to spend time with Kate, she worried that his focus on the band is slipping."She's particularly upset at present because she's frequently unable to track him down by phone or email at all."Earlier this year, it was reported Kate was jealous of Jamie's close relationship with Alison.

She was also said to be angry at his refusal to allow her to get more involved with the band, especially as her ex-boyfriend Pete Doherty had encouraged her to sing with his group Babyshambles and help him write songs.

The couple even split for several weeks, with the musician moving his belongings out of Kate's London home.

At the time, a source said: "Jamie didn't think it would be a permanent split, he just had to wait for Kate to calm down after their row.

"He loves that Kate is tempestuous but he doesn't want to be a doormat and give in to her on everything. She's starting to realise that too so is trying to be less demanding."
