R+B starlet Rihanna has named CONFESSIONS singer Usher as her first teenage crush. The PON DE REPLAY singer admits she spent her high school years obsessing over the singer. She tells MTV, "Oh my gosh! I was in love with Usher when he first came out. I was just like 'he's so fine!' I was a little girl too, I was real young. "But I really loved Usher; I thought he was the hottest thing. I think he was my first crush definitely."
