TMZ caught footage of the "lovers & friends" stepping into the same club and Rihanna also hung out backstage at the Drake Vs. Lil Wayne tour in New York. She snapped pics with Lil Wayne's daughter Reginae at the concert. 




The former couple hit up Griffin nightclub in NYC Monday night ... and according to photogs they were there for nearly 2 hours and left at around 3 AM -- 21 minutes apart. 

Eyewitnesses inside the club tell TMZ ... Drake and Rihanna had tables next to each other and were deep in conversation, flirtatious and whispering in each other's ears."
