Chanelle HayesChanelle HayesYeah, yeah, we all know that Chanelle Hayes loves a good pout.

But what exactly is she looking so misery-guts about now?

We're pretty certain she's not mooning about Ziggy any more, since she was spotted stepping out with Dizzee Rascal...

And she should be celebrating, as this pic was snapped at the launch of her new perfume.

As well as that, her reali-telly series, Wannabe, is about to kick off.

So apart from all of the above, whatever is the root of Chanelle's mood?

A-ha. It must be her hair.

I mean, seriously, the girl needs to get down the basrbers' quick-smart to sort out the majorly dark patch that is blighting the blonde, no?

Chuh. These celebs. Can afford the moon on a stick, but not a little dye job.
