Rihanna has canceled her performance at the Grammy Awards.

The R&B star was scheduled to hit the stage at the big show and she did walk the red carpet outside the Staples Center in Los Angeles, but she left after rehearsals on Monday afternoon (15Feb16) - and won't be coming back.

Nearly an hour and a half into the ceremony, Rihanna's representatives released a statement to Entertainment Weekly which reads: "Based on Rihanna's examination after Grammy rehearsal today, Rihanna's doctor put her on vocal rest for 48 hours because she was at risk of hemorrhaging her vocal cords. The antibiotics she has been on for three days did not kill the infection adequately, therefore she cannot perform safely."

Insiders tell multiple news outlets she was planning to sing Kiss Me Better at the Grammys.

It's not the first time the singer has pulled out of a Grammys appearance at the last minute - in 2009 she canceled a performance following a showdown with then-boyfriend Chris Brown on the eve of music's big night.

The Kiss Kiss singer was later charged with assault after beating Rihanna during a fight following Clive Davis' annual Grammys party.
