Jessie J, Labrinth and Calvin Harris will play Wireless 2012, it has been announced.

The festival takes place every summer in London's Hyde Park.

Writing about the news on Twitter, Price Tag singer Jessie J said: "I am Rihanna's special guest for Wireless next year!!! #booooyyaaa."

Rihanna's performance at the festival on Sunday 8 July will be her only UK live show of 2012 with tickets for next year's event on sale now.

Speaking last month about headlining the event, Rihanna said: "I'm so excited to be headlining Wireless next year! My UK fans rock and I can't wait to see them at Hyde Park."

Labrinth will also perform having just completed his own UK tour.

The 22-year-old has had top five hits in the UK with Earthquake and Let The Sun Shine.

Calvin Harris previously played at Wireless in 2009 and has had chart success with Bounce, I'm Not Alone and Feel So Close.

The Black Eyed Peas, Pulp and the Chemical Brothers headlined the 2011 festival.

Ke$ha, Tinie Tempah, Plan B and David Guetta also appeared on the bill.
