UK R&B star Ms Dynamite has signed a deal reportedly worth £1m to promote soft drink giant Pepsi.
Pepsi hope Ms Dynamite will bring them urban credibility
Under the partnership, the multi-award winning singer will spearhead a scheme to discover and nurture future British musical talent.
Pepsi says she will act as "music consultant" to the company's UK arm.
Ms Dynamite, an outspoken critic of the war with Iraq and a prominent anti-gun campaigner, takes over from Gareth Gates as the face of Pepsi in the UK.
She joins an impressive list of pop superstars such as Michael Jackson, Madonna, Robbie Williams and Britney Spears who have previously endorsed the brand.
As one of the fastest rising urban music stars in recent years, Ms Dynamite brings an undeniable street credibility to the company.

Ms Dynamite would act as a figurehead to break new musical acts, said a Pepsi spokesman.
"(The deal) broadens our current involvement within music into a whole new genre and more specifically involves discovering and nurturing new talent within the music industry," he said.
"Ms Dynamite will be involved in finding the individuals and will work closely with us in helping these new artists in their quest to make it within the music industry."
Pepsi was unable to confirm Ms Dynamite's reported £1m fee.
Pepsi is sponsoring a concert by Ms Dynamite at London's Brixton Academy on 26 April.
Later in the year, artists discovered by Ms Dynamite will be showcased at another of her concerts staged by Pepsi.
Tickets will be available only through a promotion the brand is planning for the summer.
Ms Dynamite, real name Niomi McLean-Daley, was named best female artist and best urban act at this year's Brits show.
The 21-year-old singer has also won three Music of Black Origin (Mobo) awards and sold 850,000 copies of her debut album, A Little Deeper.
