Jessie J has confirmed that she will be at London's Wireless Festival next year. 

The 'Who You Are' vocal sensation took to her official Twitter account this morning (December 9) to tell her fans the news and wrote: "I am @rihanna's special guest for #wireless next year!!! #booooyyaaa Get tickets NOW! :D"

It was announced back in November that Bajan beauty Rihanna will headline the event's closing night on July 8 and in addition to Jessie J's new inclusion on the bill, Labrinth and Calvin Harris will also treat festival goers to live performances. 

Wireless 2012 will be held at London's Hyde Park next summer, from July 6-8, and you can watch Jessie J's rendition of 'Domino' from X Factor USA here:
