Rihanna pulls out of Grammys

Los Angeles

The singer, who was to sing 'Kiss It Better' from her recent release Anti at the 58th annual awards ceremony, has been advised to give her vocals rest for 48 hours, Billboard reported quoting her representative.

The singer was at risk of hemorrhaging her vocal cords, the rep said, adding she had been taking antibiotics for three days, though the medicines did not kill the infection adequately.

Rihanna did rehearse her performance but did not walk the red carpet.
