Demi Lovato's Teen Choice Awards Gig Involves Color-Changing Hair (PHOTOS)

Demi Lovato kicked her wild fashion up a notch at Sunday night's Teen Choice Awards, where she played host with "Glee" star Kevin McHale. A typical hosting gig consists of several outfit changes (remember Anne Hathaway's eight-outfit rotation at the Oscars?) but Demi upped the ante with some drastic beauty changes. As in, her hair turned blue.

Demi's known for changing her hair color often, going bright blonde this May then debuting a trend pink ombre in June. Despite performing with her pink hair last week, Demi walked the TCA red carpet yesterday with a giant, fully blonde ponytail, the sleek look contrasting her wild, feathery, sideboob-y Falguni & Shane Peacock dress.

But she always keeps us guessing: once she hit the stage, her blonde hair was blue.

Demi's aqua ombre, we're guessing, had been wrapped up around her ponytail, which was likely made of extensions. We actually prefer the loose blue look to the severe updo -- if anyone could pull off teal lowlights, it would be Demi Lovato.

Check of Demi's fashion and hair changes. Are you a fan of Demi's wild child style or do you think she should tone it down?
