Kelly Osbourne and Matthew Mosshart are engaged, the starlet has confirmed to Hello! magazine.

Mosshart proposed during a romantic vacation in Anguilla, and he told the mag, "I knew she was "the one" pretty early on." Osbourne added, "I've never felt this close to another human being, ever. People say we're co-dependent but we just want to be together all the time." Awww!

Mosshart and Osbourne met in 2011 at Kate Moss' wedding, and they started dating about a year ago. The New York-based Mosshart recently moved to Los Angeles, and Kelly gushed, "Matthew made the biggest sacrifice anyone's ever made for me, to move away from everything that he knew to be with me in LA ... Long-distance relationships often don't work out. We'd dated for a year and knew we wanted to be together. Matthew has broken down every one of my walls. There's nothing I wouldn't do in front of him."
