The 'We Found Love' singer will head back on stage with her 'Loud' tour support, 'Feel So Close' producer Calvin, for a special charity concert.
Rihanna and Calvin Harris will reunite later this month for a one-off charity event in Los Angeles.
The 'Talk That Talk' singer has been confirmed for a performance at the House of Blues in LA on 12th February, where she will head up a bill including Deadmau5, Swedish House Mafia and her 'Loud' tour support act Calvin Harris.
The concert is being put on to raise money for charity and all proceeds from the event will be split between the Children's Orthopaedic Center and the artist program at the Los Angeles Children's Hospital.
The House of Blues charity event also takes place on the same day as the Grammy Awards 2012, which will see Rihanna take to the stage with Coldplay for a duet of their collaboration 'Princess of China'.
Rihanna is up for five Grammys at this year's ceremony including Song of the Year, Best Pop Vocal Album and Album of the Year.
The Grammy Awards 2012 are due to take place at the Staples Center in Los Angeles on 12th February.
