In celebration of the happy couple's announcement, HELLO! Online takes a look at their fairytale romance.
Stylish Kelly, 28, first laid eyes on her husband-to-be at Kate Moss' wedding in July 2011. Matthew was invited to the nuptials by the groom Jamie Hince, whose bandmate is Matthew's sister, Alison Mosshart.
Several months later, in December 2011, Kelly and Matthew went public with their romance when they were spotted embracing in New York, where Matthew was based.
"I'm in love and I don't care who knows about it!" tweeted Kelly in June 2012, as the couple's relationship continued to blossom.
One year after they started dating, Matthew relocated to LA to be closer to Kelly.
"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," the Fashion Police presenter explained.
"Long-distance relationships often don't work out," Kelly added. "We'd dated for a year and knew we wanted to be together."
Matthew has since joined his glamorous girlfriend on the red carpet several times, and in October 2012 was by Kelly's side as she watched her brother Jack Osbourne tie the knot with Lisa Stelly.
"It is lovely because the family is getting bigger," said the Osbourne's matriarch Sharon on her son's wedding day — a sentiment that's sure to extend to Matthew as he prepares to join the famous family.
In March 2013, Kelly suffered a seizure, and Matthew was there to support her and help her regain her health.
"I knew she was The One pretty early on," the smitten chef told HELLO!.
