Rihanna has reportedly sparked up a new romance with Drake.

The pop star recently called time on her relationship with US singer Chris Brown, after dating him on and off since 2008.

Rihanna is said to have since moved on with her ex-boyfriend, rapper Drake, who she was involved with in 2010 and 2011.

"When she was dating Chris, he banned her from talking to Drake," a source close to Rihanna told the latest edition of UK magazine Look. "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 realised she was over Chris."

Friends close to Drake say the star anticipated Rihanna and Chris' split. The 26-year-old chart topper allegedly never stopped loving the Barbadian beauty and even sacrificed his happiness in pursuit of her.

"[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," an insider explained.

"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."

Rihanna and Drake have been increasing communication with each other over the past few weeks. Sources say Rihanna has even started to think she made the wrong decision courting Chris over Drake.

"Since that first phone call they've been talking again a lot and have such a connection," an insider continued. "She even hinted in one message that she chose the wrong guy."

Since splitting from Rihanna, Chris has rekindled his relationship with former flame Karrueche Tran.

The pair apparently attended the BET Awards after-party at the end of May looking "loved up".
