Chris Brown & Rihanna
They were the golden couple of R&B before Chris Brown beat his then girlfriend Rihanna after a pre-Grammy party in 2009. Brown was sentenced to five years probation and ordered to complete a 52-week domestic-violence program. He was also ordered to stay 50 yards away from the singer, ten if they were at the same event. But despite RiRi condemning Brown's actions in interviews, unconfirmed reports have surfaced since the incident of the two exes getting together romantically. Brown's recent appearance on a remix of Rihanna's song "Birthday Cake" is only stoking those rumours.
