Formerly cocaine-addicted supermodel is said to have proposed to her new rock star lover Jamie Hince of The Kills just months after a split from on-off junkie-lover Pete Doherty.

Kate reportedly became engaged to guitarist Hince after they attended a friend’s wedding together over the weekend.

Kate shouted to friends: “I love Jamie so much - we’re engaged!”

“They’re clearly in love with each other,” a source tells the British tabs.

“Kate and Jamie had been together all night and day until 5pm and when they surfaced Kate told her friends that she and Jamie were engaged.”

“They had spent the night making love and Kate asked him during that. He was overjoyed because that’s what he wanted, too…..”

“No one thinks they are actually going to walk down the aisle any time soon - they know it was Kate’s way of saying she’s serious about him.”

“Everyone knows it’s a message to Pete too, telling him she’s moved on and is happy with her new man.”
