Diet Coke to launch Duffy ad during Brits

The 60-second ad, created by Mother, stars Duffy alongside other confident young women who are taking a stand against the pressures of modern life.

It shows the 'Mercy' singer leaving the stage after a sell-out gig as the audience calls for an encore. Before delivering the finale she spots a bike propped up backstage and cycles off singing the soul classic 'I've Got To Be Me', made famous by Sammy Davis Jr in 1968.

The lyrics are supposed to reflect the Diet Coke campaign, celebrating a woman's right to express her individuality and take control.

Duffy said: "One thing I like to do, my way to rebel on tour if you like, is to take off on my own and turn my phone off.

"It feels slightly naughty but it's important to have those moments."

Cathryn Sleight, marketing director, Coca-Cola Great Britain, said: "Since the brand launched, it has always celebrated women, their lifestyles, attitudes and aspirations.

"We're very proud of this new campaign which shows strong and confident women taking control and saying no.

"Duffy, as a young woman who is in charge of her own destiny, perfectly embodies the independent attitude we're championing."

The ad will air during the live broadcast of the Brit Awards on ITV1 from 8pm-10pm on February 18.
