The Pop star was scheduled to perform near the beginning of the show, but failed to attend after her doctor ordered her to rest her voice for two days, or risk haemorrhaging of her vocal cords.
She had a throat infection and had a medical examination after Monday’s rehearsal for the show.
Rihanna, an eight-time Grammy winner, was reportedly scheduled to perform ‘Kiss it Better’ from new album Anti.
She is however, still due to perform at the Brit awards next week.
Meanwhile, Grammy organizers were expecting Lauryn Hill to make a surprise appearance during The Weeknd’s performance Monday night, but the singer was a no-show.
Recording Academy President Neil Portnow said Hill showed up for a dress rehearsal Monday morning but left and didn’t come back.
