The couple were rumoured to be casually dating in 2011. Rihanna later confirmed the reports, though she said it was never serious.
However, the pair were spotted looking "hot and heavy" together on the dance floor at the Miami club Liv on Sunday night (May 27).
"Rihanna was all over Drake this weekend," a source told Us Weekly. "They were holding hands and dancing all close on the dance floor."
Drake was recently spotted on vacation with Tyra Banks, sparking rumours that the pair had become involved romantically.
The rapper previously admitted to living a promiscuous lifestyle, though he said he did not enjoy it.
