Christina aguilera goes back to the long look

New York Fashion Week is always a great time for a party - all the coolest people in the world are in one place, so no matter how rubbish your do, you're still guaranteed a good turn out. Smart, eh?

Christina Aguilera - and her new extensions - celebrated the launch of the Montblanc John Lennon Edition last night - yes, that's right, a party for a pen. It's actually a pretty good idea (read more about it here), but in the midst of the glittering fashion week events, a pen isn't quit up there with Chanel, is it?

Christina is one of a host of celebs who has gone back to the world of long, flowing extensions. What with Victoria Beckham and Cheryl Cole reverting back to the fake look, it appears that there's still a huge demand for the uber-glamorous lengthy, style.
