Kelly Osbourne and fiance Luke can't be separated on New Year's Eve... not even in the DJ booth

The Spice Girls famously sang 2 Become 1 and it seems that Kelly Osbourne and fiance Luke Worrall are happy to become just that as the pair locked lips at club Mahiki last night.

Rocker Ozzy Osbourne's daughter and the 19-year-old male model saw the New Year in the young royals's favourite haunt, with Luke taking a turn on the decks.

But it seems they couldn't bear to be separated as they puckered up to one another while Luke tried to mix tunes.

Dressed in a cheeky sailor hat, and sparkly jacket, Kelly, 24, looked ready to party as boyfriend Luke spun the tunes.

Earlier in the evening the reformed wild child and her model boyfriend headed for a slap-up meal at a trendy eaterie Sakenohana.

Unfortunately, it didn't quite put any colour into her paler than face cheeks.

Meanwhile, Kelly has spoken of her friendship with supermodel Kate Moss and revealed, she's just like a normal person.

‘She is really down to earth', says Kelly. 'One thing I respect about her is she doesn’t tolerate meanness. She’s not malicious.

‘If she sees someone in our group being mean to someone else, she’ll put a stop to it. She’s a peacekeeper.’

And surprisingly Kelly, who has been subject to her fair share of fashion faux pas says she doesn’t go to Kate, 34, for wardrobe advice.

She told the Sunday Mirror: ‘I don’t ask her for fashion tips or anything. When we’re together we’re just friends.’

They have only been dating for four months but could Kelly Osbourne and Luke Worrall be about to tie the knot?

The couple seemed more loved up than ever after a romantic evening in London last night.

As if to prove her commitment to her model beau, Kelly, 23, certainly wasn't shy when it came time to wave the ring on her engagement finger around in front of photographers.

It remains unclear if the daughter of rocker Ozzy and X Factor host Sharon is planning to walk down the aisle with Luke, 18.

But the pair couldn't keep their hands off each other as they went for dinner at trendy Mayfair restaurant Nobu before hitting nearby club Bungalow 8 with her brother Jack and friends including actor Adrian Grenier and Kimberley Stewart.

Kelly wore a cute bowler hat as well as the ring she was first spotted wearing in July.

And although there is still no confirmation of an engagement, the pair's relationship is showing no signs of cooling down just yet.

Despite heels and a short skirt, Kelly Osbourne proves she can still leg it

Kelly Osbourne was in a fit of giggles as she raced to be first on board a minivan.

The TV presenter laughed hysterically as she and friend and E4 host Nick Grimshaw legged it from the Radio One studios on to the vehicle.

Osbourne, 23, and Grimshaw, 24, were leaving the central London studios and in a bid not to be a 'rotten egg', jostled and pushed each other from the door in an attempt to make it on board first.

They had previously met up at the V Festival at Hylands Park in Chelmsford at the weekend, where Osbourne was seen watching bands with her latest beau, Luke Worrell.

Grimshaw, who appeared to be wearing the same clothes he wore at V, was co-presenting from the festival for 4Music.
