“When she was dating Chris, he [asked her not to talk] to Drake,” a source told Look magazine. “She really missed him in that time – yes, they went out years before but he was also a good friend to her – so calling him was one of the first things she did when she realized she was over Chris.”

Drake, 26, allegedly knew Rihanna, 25, would come back to him once she ended things with Chris, 24.
“[Drake's been] waiting patiently on the sidelines. Just over a month ago, Drake gave Rihanna an ultimatum. He told her he needed to move on if she wasn’t going to commit. His love life was paused when Chris and Rihanna reunited, and Drake claims it caused him stress headaches, writer’s block and anxiety. He was obviously sick of it, but Rihanna wasn’t ready for him. Now Chris and Rihanna are done for good, Drake might finally get his chance,” an insider says.

Chris and Rihanna allegedly hooked up for more than a year before publicly confirming their rekindled romance in late 2012. Sadly, their relationship ended five months after that, as Chris announced in May that he was single again. Now, Rihanna is allegedly starting to believe that it’s Drake who is the one for her.
“Since that first phone call, they’ve been talking again a lot and have such a connection. She even hinted in one message that she chose the wrong guy,” the insider adds.

Drake recently talked about Chris and Rihanna’s reunion in GQ magazine and said he could see it “ending badly.”

“If I think about it too much, I feel it wrapping around my foot, like I get a feeling it could end really badly,” he said, “Like, it gets really dark.”
