Are Rihanna and Chris Brown getting back together following her birthday surprise for him? Rumor has it, RiRi successfully made her ex "speechless" when she sang him happy birthday on his 28th birthday via FaceTime.

At that time, RiRi apparently called Breezy to say, "I love you," and he said it back without hesitation. According to a source, that's when they made plans to hangout again sometime soon. "The plan is to hopefully link up when their respective schedules allow it," the source tells HollywoodLife.com.

Through all their ups and downs, there's still a comfort level that turns both RiRi and Breezy on! "To be out on the town with her again and turning up, would be just what the doctor ordered," adds the source.

A source close to RiRi previously revealed about her birthday surprise, "Rih was not about to let this day go by without hitting Chris up on his birthday. They FaceTimed and when he picked up she immediately started singing him happy birthday. He was speechless [as] his eyes lit up and he had the biggest smile on his face."

The insider continued, "He was bobbing his head when she was singing and when she was done he was like wow." Not only did RiRi sing him happy birthday, the "Umbrella" hitmaker reportedly also told him three magic words, "I love you." "They talked briefly and she told him I love you," the source added.
