Superstar Rihanna debuted her new natty dreads hairstyle Wednesday night during the 2012 American Idol Final Results show. Rihanna whipped her butt length dreads back and forth while performing her hit single “Where Have You Been” during the Finale.

Earlier, Rihanna tweeted a pic of her new dreads extensions, shocking her fans who doubted she was really making the transition to dreads.

Rihanna told her fans on she long wanted dreads since she was 14, but her mother wouldn’t allow it. Another follower asked Rihanna if her new hair was heavy. Rihanna responded: “as Goliath’s balls.”
