US magazine People says, "They're together again. They care for each other."

And apparently the two young stars have been spending time together at P Diddy's house at Miami Beach.

A source also told People, "While Chris is reflective and saddened about what happened, he is really happy to be with the woman he loves."

They also added that Chris has been enjoying himself with water sports during the holiday and was seen, "smiling, riding a jet ski, and flexing his arm muscles."

So far there have been no confirmations of the reunion but Rihanna's father has said, "I love my daughter with whatever road she takes. I'm behind her win or lose. I will be supportive. If that's the road she wants to choose, I'm behind her. I hope to see her soon. I talked to her after her birthday, and she told me she's OK."

What are your thoughts on the reunion?
