LOS ANGELES (REUTERS) - Prince and George Michael will be honoured at the Grammy Awards on Sunday (Feb 12) with separate tributes, but organisers did not say on Wednesday (Feb 8) which musicians will perform them.

Recording Academy President Neil Portnow said Purple Rainsinger Prince, and British star Michael, who both died suddenly in 2016, were "pop icons who showcased rare musical genius and otherworldly charisma."

"The passings of two such creative innovators were a huge loss for the creative community; The Recording Academy is humbled to pay homage to their tremendous legacies on the Grammy stage," Portnow added in a statement.

The Recording Academy said it was not announcing details of the tributes and who will participate.

Prince, a seven-times Grammy winner, was found dead at his Minneapolis studio complex in April. An autopsy revealed the 57 year-old died of an accidental overdose of the painkiller fentanyl.

Michael, 53, known for songs like Last Christmas andFreedom, was found dead at his British home on Christmas Day. The double Grammy winner's manager said the singer died of heart failure, but the official cause is still being investigated.

David Bowie, who died in January 2016, was honoured at last year's Grammys in a tribute performed by Lady Gaga.

Bowie's final release, Blackstar, is competing for four Grammys at the awards show in Los Angeles on Sunday, including best alternative album.
