The couple first got together for a brief period in 2009 before splitting. Now, the two are said to be seeing each other casually, according to the New York Post.
"They are definitely attracted to each other," a source said. "She's all about her career, and he wants to date around."
Drake told the New York Times in 2009 that he felt used by the 'S&M' singer.
"I was a pawn," Drake said. "You know what she was doing to me? She was doing exactly what I've done to so many women throughout my life, which is show them quality time, then disappear. I was like, 'Wow, this feels terrible'."
Rihanna recently revealed that she is good at masking her emotions, stating that her relationship with Chris Brown had a negative impact on her outlook on life.
Last week, the 23-year-old said that any man wanting to date her needs to "earn" her love, claiming that she particularly likes men who can make her laugh.
Over the weekend, a fire broke out at Rihanna's concert in Texas and caused the show to be postponed.
