We all remember when Rihanna pulled the plug for her Victoria's Secret performance last year – and left everyone very disappointed. Well, now the singer cancelled another big show at the last minute.

The 27-year-old was set to perform at the Grammy Awards last night, until her rep had to cancel for her a few hours before the gig.

She was going to sing Kiss It Better, a new track from her album, and even rehearsed twice for her performance until her doctor told her the show just couldn't go on. 

According to TMZ, Ri was taking antibiotics for three days prior to her performance but they didn't work.

After her second rehearsal she was checked by an on-site doctor who told her she would be at risk of damaging her vocal cords if she went on.

We just hope she gets better and can take to the stage to kill at her next gig.
