Rihanna was a no-show at the 58th annual Grammy Awards on Monday, where she was scheduled to perform.
According to TMZ, the pop star had to cancel her appearance due to bronchitis.
A doctor reportedly warned the singer that performing could permanently damage her vocal chords.
Rihanna was slated to perform her new song 'Kiss It Better' about an hour into the show, with 'The Late Late Show' James Cordon introducing her, but CBS' broadcast cut straight to the Best Country album award with Corden joining host L.L Cool J.
Her rep says that the singer's doctor put her on vocal rest for 48 hours because she "was at risk of hemorrhaging her vocal cords." Rihanna had been taking antibiotics for three days, though the meds "did not kill the infection adequately."
She arrived at Los Angeles' Staples Center to rehearse her performance but did not walk the red carpet. She "killed it at rehearsal," per a source. The last-minute cancelation comes several days after she debuted her Fenty Puma by Rihanna collection in New York City on Friday.
Rihanna is expected to embark on her Anti world tour later this month.
