Kelly Osbourne 'secretly engaged' to Matthew Mosshart

London, Jan 24 (ANI): Kelly Osbourne is reportedly engaged to boyfriend Matthew Mosshart, who is said to have popped the question shortly before Christmas, and now the couple are said to be planning a summer wedding.

A source told Us magazine that the couple are "really excited" about planning their nuptials, the daily mail reported.

"Kelly is the happiest she's ever been. Her career is going well, and she's in a healthy relationship with a wonderful guy," the friend added.

Kelly and Matthew met at the nuptials of Kate Moss and Jamie Hince in July 2011, but didn't go public with their romance until five months later.

The TV presenter has credited her beau with helping her achieve her super-slim figure - thanks to his healthy cooking.

She said that over the past two years, she's lost over four-and-a-half stone (63 pounds) - but she's only lost the last stone since she met Matthew.

She recently spoke about her love for Matthew and said he made her realise what real love is. (ANI)
