Rihanna @ Letterman

Rihanna rocked the house Thursday night, performing her hit single “Shut Up and Drive” on The Late Show with David Letterman. The Barbados babe carried her pet pooch named DJ, in and out of the Ed Sullivan theater.

FYI: Rihanna toted around the Abbey bag by Zac Posen in amethyst (the same one Rachel Bilson sported back in July).
