Last night Bajan siren Rihanna performed her No. 1 Billboard smash “What’s My Name” on the  Late Show with David Letterman. In a hot Dolce & Gabbana polka dot getup and her new long red hair, she belted out the pop love song. Rihanna’s doing well using her island culture for mainstream success  and sounded pretty good. She’s not known for powerful vocals, but she’s no slouch either. Check out the performance and let us know what you think.

Rihanna’s LOUD is in stores now. Have you gotten it yet? Will you?
