Here’s Chris Brown and Rihanna getting hot and heavy in the water — and this is the first photo of them as a loving duo!

R&B’s most secretive couple were sharing a romantic weekend in Jamaica and we can say for sure guys, the cat is out of the bag.

The Grammy winner, who was thrown a big birthday bash by Chris for her 20th birthday last week, was all over her younger man. “They were smooching in the pool and were really lovely dovey,” a spy reports. “They were playfully making out and he was kissing her on the neck.”
