On Good Morning America, Rihanna made a visit to sing her heart out to the crowd in a bedazzled white and silver dress-only to find her glamorous outfit was too small. 

Rihanna busted her zipper just one minute before the teenage pop star went live, she recalls how her wardrobe was too snug and didn't have time to fix it. Luckily, the performance went ahead as planned without a mishap, and got her face onto the TV screen.

Rihanna had gained some weight possibly due to her break up with ex Chris Brown, and because she's spent a considerable amount of time in the recording studio pumping out heart-break tracks.
