 A week ago, MTO reported that Rihanna was expecting a child for either Chris Brown or Drake (read here)...well, rather than tweeting to refute the rumour, she stepped out yesterday wearing a bright bra top to exhibit off her very flat stomach. She went to The Supper Club in Hollywood yesterday evening with new boyfriend, Drake.
