KATE MOSS's relationship with rocker boyfriend JAMIE HINCE is reportedly on the rocks again after he struck up a friendship with a PR girl on tour in Australia.

Jamie and his band The Kills have been on a gruelling jaunt around America, New Zealand and Oz.

According to British reports, Kate wasn't pleased when she heard Jamie had become friendly with NICCI HUNTER, who works for Australian clothing label Sass & Bide.

A source tells tabloid, "Word reached her that Jamie became quite friendly with Nicci. She cut short her holiday to the Maldives with Jamie earlier this year because they were fighting so much. Now she and Jamie haven't seen each other for weeks. She hasn't wanted to join him on tour."

Hunter insists her friendship with Hince is innocent, adding she met him through his Kills bandmate Alison Mosshart.
