Pixie Geldof is at it again. 

She's been doing the strand shuffle in a major way.

This time Bob Geldof's daughter has transformed her crown to candy-pink.

So what's up with the makeover?

Well, it seems that Pix has just been getting wiggy with it, all in the name of Christmas cheer.

The socialite/model/whatever donned the wig for her Christmas party at Bungalow 8 in London, last night.

Apparently the party had a dress up theme - what it was we're not quite sure. Alexa Chung and Alex TurnerAlexa Chung and Alex Turner

The party appeared to be quite the riot with some of London's coolest kids, including Sugababes and Alexa Chung - who came dangling on the arm of her boyf, Arctic Monkeys' Alex Turner.

Alexa chose to rock an odd mix of leopard print and a painted-on Zorro mask. Strange.

Even Josh Hartnett made an appearance at the bash. 

Who knew 18-year-old Pix had so many influential friends?

And folks, it gets better, apparently Pix and bestie Alexa belted out Madonna's Papa Don't Preach on karaoke.
