When their faces are going to be televised across the world, you can't blame top singing talents for wanting to make sure their smiles light up the screen.
Which is why so many of them have been having their teeth whitened of late.
Brit nominees Duffy, Adele and Girls Aloud have apparently been to see 'smile specialist' Dr Wyman Chan at his London clinic to improve their gnashers.
Duffy and Adele as well as Cheryl Cole, Sarah Harding, Nadine Coyle, Nicola Roberts and Kimberley Walsh had the Wy10 Whitening System which whitens teeth up to eight shades in an hour.
And if you're thinking of following suit, get in quick because while everyone's feeling the pinch, the clinic is offering the treatment at just less than half price - £295.00 instead of the usual £595.00 for a limited period.
