Rihanna, Calvin Harris, The Wanted To Play Jingle Bell Ball 2011

Rihanna has been confirmed to appear at this year's Jingle Bell Ball.

The singer will join other acts including Olly Murs, The Wanted and Pixie Lott at the annual concert, which will take place on December 3 and 4.

Calvin Harris and Jason Derulo have also been confirmed to perform at the show at London's O2 Arena.

Rihanna's appearance will mark her 11th at the venue this year, as the singer sold out a record-breaking ten dates at the venue as part of her 'Loud' world tour.

Last year's lineup featured sets from Kylie Minogue, JLS, Tinie Tempah and The Saturdays.

Tickets for the first day of the two-day event are on sale now. The Jingle Bell Ball's second day of acts will be unveiled soon.
