When it comes to high drama, the Osbournes are never far away.

If they are not falling off quad bikes or burning down their house, they can usually be found neck-deep in some verbal row with a fellow celebrity.

But Ozzy's little girl Kelly dramatically upped the ante last night when she slapped a fellow clubber in the face.

The 23-year-old wildchild and sometime TV presenter was out at the Smash and Grab night at Punk nightclub in Soho last night.

The night started off well enough, with Kelly attending the Portobello Film Festival for the premiere of the short film The Town That Boars Me  -  in which she stars.

She left with Paul Weller's son Nat but was later spotted at Punk, quaffing champagne and getting out on the dancefloor with a few of her mates.

But things turned sour when she spotted a gossip columnist (no, not us!) and made a bee-line for her.

A source said: 'Kelly was dancing with a female friend, then saw someone she knew and went and started talking to them.

She sat down next to the girl and looked like she was telling her off. I heard her say 'you better watch your back'.

'She then slapped her around the face and stormed out of the club. It was particularly funny as she had a black eye.'

The source added that Kelly was a bit miffed because the hack had written a less-than-flattering article about Kelly's boyfriend Luke Worrell  -  suggesting that he was 'dim' for not knowing what an earthquake is.

It hasn't been a great week for Kelly. She had to dash home from the Reading Festival at the beginning of the week because she reportedly contracted a stomach bug.

She then stepped out on Tuesday with a nasty gash over her left eye and an impressive shiner (a kitchen cupboard fell on her, cutting her face).

Now she's picking fights in nightclubs. Whatever next?
