Kelly Osbourne's engagement ring

Kelly Osbourne's engagement ring

Kelly Osbourne has shown off her engagement ring on Twitter.

The 28-year-old star - who announced her engagement to chef Matthew Mosshart last week - unveiled her diamond band in a snapshot of her new manicure on Saturday (20.07.13) after she indulged in a salon session at esNAIL in Los Angeles with her rocker dad Ozzy Osbourne.

She posted a picture of her new glittery silver nails, complete with a black cross on the middle finger of each hand, with her large sparkler clearly visible on her ring finger.

Kelly added: "Loving my new manicure thank you #esnails (sic)"

Her fans jumped in to congratulate her, writing gleeful messages including, "beautiful engagement ring Kelly!! congrats", and, "So happy for you. You deserve it!"

The 'Fashion Police' star then shared a picture of her father's hands intertwined with her own, alongside the words, "My dad got his nails done too! Look how cool they look!"

Ozzy's black talons, each marked with a cross, were set off by a large gold skull ring.

Matthew popped the question to Kelly during a holiday to the Caribbean island of Anguilla on New Year's Eve (31.12.12), but the pair have kept their engagement secret until now.

The father-daughter pictures are fitting since Kelly's custom-made silver ring was designed to look like an old earring belonging to Ozzy.

She previously said: "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!"
