Rihanna and Chris Brown
When rising stars Chris Brown and Rihanna met, the relationship had a profound effect on both of them. Of Brown, Rihanna said, "I have to act and think like an adult so much. He makes me feel young again." The teenage romance ended tragically when Brown assaulted Rihanna in a rented Lamborghini on the way home from a pre-Grammy party. She had to cancel her Grammy performance and Brown was sentenced to six months of community service and five years probation.
