Osbourne starlet Kelly last week announced her engagement to boyfriend Matthew Mosshart. While getting her nails pimped with daddy Osbourne, the Fashion Police host papped a photo of her nails; glittering engagement ring impossibe to miss…

The couple, who reportedly got engaged in Anguilla at New Years have been keeping the news under wraps, and what a difficult secret that must have been for the loved-up duo to try and conceal. “I have never felt this close to another human being, ever. People say Matthew and I are co-dependent, but we just want to be together all the time,” Kelly told Hello Magazine. Awww.

The bling-tastic engagement ring was custom designed by Kelly herself, fabricated to look like an earring her superstar father wore: “I designed it to look like an earring that my father wore. 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!”

“As long as Kelly’s happy, I’m happy,” family matriarch Sharon told Celebuzz. “That’s it. That’s the way it goes. I do happen to adore her boyfriend,” she added.

Looks like our favourite disorderly family are all grown up! Kelly’s engagement comes just months after Jack’s wedding to Lisa Stelly, who’s also the mother of his daughter Pearl. The engagement shouldn’t come as a complete surprise, however, considering Jack did hint at the impending nuptials: “Yes! Kelly is engaged to Matthew, and that will be the next wedding,” he told People back in February.

Niece Pearl is rumoured to be ring-bearer at Kelly’s wedding, suggested to take place at the house in Buckinghamshire where she grew up.
