T.I. will join Ludacris, M.I.A. and LCD Soundsystem as a headlining performer at the annual Virgin Mobile Fest in September.

Virgin Chairman, Sir Richard Branson, announced the festival lineup on Tuesday (July 19) via the company's new web TV show, Virigin Mobile Live, while Virgin Mobile FreeFrest concert producer Seth Hurwitz explained that this year's festival aims to feature a solid selection of popular performers.

"Because we have the luxury of giving away the tickets it becomes a privilege to book the most important acts out there," Hurwitz said. "Our goal is simply to book the coolest bands we can. This year we're breaking with the traditional format of monster headliner trickling down to baby bands, and instead we're sprinkling fantastic acts all day long. It's kind of like a festival on full-day shuffle."Other performers at Virgin Mobile Fest will include Jimmy Eat World, Chromeo, Temper Trap, Die Antwoord and Matt & Kim. The concert will be held at Merriweather Post Pavilion in Columbia, Maryland on September 25. Fans can score tickets to the free festival by logging onto ticketfly.com at 10 a.m. on Saturday, July 24.

T.I.'s upcoming album 'King Uncaged' is currently slated to hit stores on September 28, three days following his performance.
