Kelly Osbourne is head over heels in love. The 28-year-old revealed earlier in the year that her boyfriend and celebrity vegan chef Matthew Mosshart was the one and now she has the beautiful diamond sparker to prove it.

The "Fashion Police" co-host confirmed the engagement rumors by showing off her diamond ring (see it here) to Hello magazine. She said Mosshart got down on one knee while they were vacationing in the Caribbean and popped the question. 

"We were on a balcony that overlooks the ocean," Mosshart told Hello. "It was just beautiful. She said yes! And then she smiled for the rest of the night!"

"I've never felt this close to another human being, ever," Osbourne added. "People say we're co-dependent but we just want to be together all the time."

She told the magazine that her engagement ring was designed with her father in mind and holds a lot of sentimental value. 

"I designed it to look like an earring that my father wore," she said. "I used to hold my finger up to his ear when I was little and say, 'I want a ring like that.' Now I have one!"

Osbourne and Mosshart reportedly met in 2011 at supermodel Kate Moss' wedding to rocker Jamie Hince, the New York Daily News reports. From early on they both knew they were in it for the long haul with Mosshart revealing to Hello that he "knew she was The One pretty early on."

Maybe that's why the chef had no problem leaving his New York City life behind to relocate to Los Angeles so he could be closer to former reality TV star.

"Matthew made the biggest sacrifice anyone's ever made for, to move away from everything that he knew to be with me in LA," she said. "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."
