Both stars were seen leaving the same recording studio in NYC around 1AM on May 9.
Reports say the on-again, off-again couple spent three hours in the same studio creating a new sound together or are they back on the dating business?
Their hits, 'Take Care' and 'What’s My Name?' both landed in the Billboard Top 10 — so it looks like they could be at it again!
For her studio session, RiRi kept it casual, donning black jeans and an oversized t-shirt while allowing those long red locks fly with the early morning breeze.
Funny thing is the stars' studio night together comes just one day after they partied together at Game nightclub in New York City, where the rapper was hosting a party. But her alleged beau, Leonardo DiCaprio was also in the building.
