Kelly Osbourne kept her engagement secret for more than six months after her long-term boyfriend Matthew Mosshart proposed over the New Year holiday.

The pop star-turned-Tv personality and Mosshart revealed their news in this week's (begs15Jul13) issue of Britain's Hello! magazine, and in the accompanying interview, they admitted they have been engaged since the start of 2013.

The vegan pastry chef whisked his girlfriend to Anguilla for New Year's Eve (31Dec12), and popped the question in the early hours of New Year's Day (01Jan13).

Mosshart says, "At 2am, when the festivities had wound down a little, I tried to pull her away from everyone. I got down on one knee... we were on a balcony that overlooks the ocean. It was just beautiful."

Osbourne, who had previously told her partner it was her dream to be proposed to in Anguilla on New Year's Eve, adds, "I started to cry."

The couple has already started planning the ceremony for next year (14), with Osbourne admitting she wants to marry at her childhood home in England and recycle the material from her mother Sharon's wedding dress for her own gown.

She adds, "I want to marry in the house I grew up in... we don't want to rush it, especially as my brother Jack got married last October. I also want to wait until my niece Pearl, who is 15 months, can walk down the aisle as ring bearer.

"We are taking the lace from my mum's wedding dress and making mine with it. It's something she's said she'd like me to do since I was a baby."
