Rihanna Shows Off Her Taut Tummy

She's known as the good girl gone bad. But, for Rihanna, it was more a case of good girl gone shopping on Sunday - a she proved when she stepped out for a music-related spree at Best Buy and Amoeba Music in West Hollywood. The chart-topper, 27, shared an image of herself buying the latest release by acclaimed hip-hop artist Travis Scott - the man who co-wrote her latest single, B**** Better Have My Money.
