N-Dubz lead singer Dappy will join English rap sensation Professor Green and X Factor winners Little Mix on the stage at this summer's T4 on the Beach.
The Weston-super-Mare summer spectacular on July 1 will also see performances from Rizzle Kicks, Cover Drive and Labrinth.
Organisers T4 made the announcement of its first six artists tonight, and has promised further additions to the line-up in the coming weeks.
Up to 50,000 music fans are expected to head to the Somerset resort to celebrate the tenth anniversary of the T4 on the Beach open-air event, and many will be excited by the addition of Dappy and Professor Green to the line-up.
Now established as a solo artist, Dappy's debut solo single went to No.1, and his latest single Rockstar has also earned rave reviews from critics.
Dappy will also be performing tracks from his debut solo album Dare to Dream, to be released soon.
Professor Green has won legions of fans after his first two albums Alive Till I'm Dead and At Your Inconvenience. He's currently working on a third album, possibly to be released in time for T4 on the Beach.
Little Mix are enjoying their first year as a group. Originally four solo artists, the girls were put together as a group during the judging process of last year's X Factor, which they went on to win.
Hip hop duo Rizzle Kicks' debut album Stereo Typical was released back in October, their popular singles include Down With The Trumpets and Mama Do The Hump. They've also remixed tracks by Jessie J, Ed Sheeran and Olly Murs.
Cover Drive are a four-piece band from Barbados whose hits include No.1 single Twilight and Lick Ya Down, while Labrinth will release his debut album Electronic Earth next month.
