America's expensive smileAmerica's expensive smileIt's official: someone out there has a million dollar smile.

And if you saw it on TV you'd never believe who it belongs to...

We're talking about Ugly Betty star America Ferrera, whose smile has just been insured for a whopping $10 million (£5m).

Fret not, the starlet isn't turning into a diva like her Mode counterparts. It's all in the name of charity.

Aquafresh White Trays has secured an exclusive insurance policy for America's smile as part of a programme to raise money for the organisation Smiles For Success.

The policy is alleged to be one of the most valuable ever granted by Lloyd's of London for a single body part.

Other body bits said to be on Lloyd's list are Keith Richards' fingers and Santa's beard(?!).
