Alexa ChungAlexa ChungAlexa Chung is celebrating getting a pair of expensive handcuffs.

The metaphorical kind, you understand.

The Popworld presenter has signed an exclusivity deal, tying her to Channel 4.

Of course, her face is already all over the channel, as she's been doing odd stints on Big Brother's Big Mouth and T4, as well as being at the Popworld helm.

But Alexa's new, juicy Channel 4 contract will see her become a regular face on T4 and music breakfast show Freshly Squeezed.

She'll also front a new reality show arriving on the channel in 2008.

The show, which will examine ideas of beauty, sounds a bit like Next Top Model meets Big Brother, with a bit of How To Look Good Naked thrown in for good measure.

But who exactly is this Alexa chick anyway?

What was she up to before Popworld found her? Is she really smooching Arctic Monkeys' Alex Turner? Or is she actually snogging Holly Valance?
