Singer Rihanna performs ''Say You, Say Me'' at the 2016 MusiCares Person of the Year gala in Los Angeles, California February 13, 2016.
A throat infection forced the 11th-hour cancellation of a Grammy show performance by recording star Rihanna, whose doctors ordered her to rest her voice for 48 hours or risk the hemorrhaging of her vocal cords, organizers said on Monday.
In another last-minute Grammy no-show, hip-hop artist Lauryn Hill inexplicably failed to appear for a planned, but unannounced, duet with R&B star The Weeknd despite a dress rehearsal with him earlier in the day, said Neil Portnow, president of the Recording Academy.
