Kelly Osbourne secretly did the deed at Christmas, according to US reports

Kelly Osbourne is secretly engaged, according to US reports.

Matthew Mosshart popped the question a few weeks before Christmas and now the couple – who have been dating for around 18 months – are ‘really excited about planning their wedding.

Kelly is the happiest she’s ever been,’ a source told US Weekly. ‘Her career is going well, and she’s in a healthy relationship with a wonderful guy.’

The wedding is set to take place in the UK this summer.

Kelly, 27, 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.

Kelly recently said of Matthew: ‘I don’t think I’ve ever really known what love is like before.’
