Kate Moss' latest romance has broken another heart apart along with her ex-lover PETE DOHERTY - her new boyfriend JAMIE BURKE's live-in girlfriend JESSIE LEONARD.

The supermodel, 32, started dating 20-year-old barman JAMIE BURKE, after meeting him while snowboarding in Aspen, Colorado, over Christmas (DEC05).

The news has stunned Australian model Leonard, 24, who has been dating Burke for two years and lives with the hunk in New York City.

Burke's boss, SCOTT LONG, of New York nightclub Scenic, says, "None of us had any idea that Jamie was with Kate Moss. Jessica is going to be very hurt by this. As far as we all knew, she and Jamie were very much in love."

Leonard's model agent PRISCILLA LEIGHTON-CLARK confirms her client has returned to her native Sydney after hearing of Moss and Burke's relationship.
