Girls Aloud to reveal sweet side?

Girls Aloud are reportedly planning on 'having a break' - but not from their work as pop stars.

Instead, the girls have apparently signed up to front a new ad campaign for KitKat.

Although the final details are reportedly being thrashed out, it's thought they'll promote a low calorie version of the chocolate bar.

The deal is expected to bag Cheryl, Nadine, Sarah, Nicola, and Kimberley, a huge pay cheque.

Reports say the girls will be at the centre of a huge campaign, including TV, advertising and headline tour sponsorship.

Girls Aloud have already endorsed ad campaigns for Sunsilk shampoo and Samsung mobiles.
