Diet Coke ad starring Duffy: Watch it here

LONDON - Diet Coke is unveiling its new ad campaign featuring the Brit-award nominated singer Duffy during ITV's coverage of the awards tonight at 21.58pm.

The 60-second ad, which will also run across Europe, was created by Mother and features the Welsh singer taking a "Diet Coke break" before performing a gig.

During her break, the singer takes a sip of the drink before riding around on a bike and singing a cover of the Sammy Davis Jnr song I Gotta Be Me.

The ad, which marks a departure from Diet Coke's series of "hunk" ads, aims to show an image of women as strong, confident and in control.
