Kate Moss had a furious argument with her boyfriend after discovering he had a vial of his ex-girlfriend's blood.
The British supermodel became incensed when she discovered the gory keepsake alongside love letters Raveonettes frontwoman Sharin Foo had written The Kills rocker Jamie Hince, and is now convinced her boyfriend is still infatuated with Sharin.
A source said: "Jamie has always been a romantic, when he falls for someone he's completely engrossed in them. Jamie and Sharin took to wearing each other's blood in vials around their necks and exchanged romantic notes when they were away on tour. Jamie kept them all.
"He could never bring himself to throw them away. But now Kate's found them she's gone through the roof. She has demanded to know why Jamie had all these reminders of a past relationship."
Kate - who reunited with Jamie last month following a brief split - is said to be so angry about the discovery because she has always been jealous of Sharin.
The catwalk beauty - who previously dated Babyshambles rocker Pete Doherty - is now struggling to accept how important Sharin was to Jamie at one time.
The source added to Britain's The Sun newspaper: "The Kills used to tour a lot with the Raveonettes and there was an instant spark between Sharin and Jamie. Once they were on the same bill at a concert in London and it was like there was nobody else in the room but Sharin. Jamie was up close and deep in discussion with her while everyone else partied afterwards."
Kate and Jamie are believed to have gone to her luxury home in the Cotswolds at the weekend to discuss the future of their relationship.
