It's beginning to feel a lot like Christmas, especially when celebrities set aside the edicts of style to dress up in festive fripperies and get the party started.

This kind of antic is thin on the ground in image-obsessed Hollywood, but thankfully Audrina Patridge was happy to show off her fun side today at a party to celebrate the holidays today.

And that's not all she showed off, as the 26-year-old brunette donned a sexy santa outfit that clung to her slender frame in all the right places.

The beauty donned what appeared to be a customised Herve Leger bandage dress in the brightest red, with sexy black boots and that all important Santa hat.

She told iPad entertainment news provider The Daily: 'I don't like to talk about that. Well, see I have this chest problem. My bone right here, it's higher on this side? It's pectoralis something. So I've always struggled with that. You could see they look different sizes all the time.'

She says that she's sick of comparisons to former co-star Heidi Montag, who famously got ten plastic surgery procedures in one day.

'I always get asked about that because of Heidi and there’s all these rumours and they all say I’ve had, like, six procedures, and I’m, like: Where do you get that?'

'Look at the pictures. I fluctuate in weight a lot. And as far as my face, I’ve never had anything done.'

Audrina weraing Herve Leger was flanked by two toned hunks at the party.
