Ocean also sent out a few tweets about their studio time, "Just played nas a song...on piano," he wrote. "in that moment i realized, im getting a lil better at piano. i gotta keep practicing though."
If the two are in fact working together, the new music will most likely appear on Nas forthcoming 10th release. As previously reported, the 37-year-old put his highly anticipated 'Lost Tapes 2' album on hold to work on his current LP following his successful 'Distant Relatives' collaboration with Damian Marley.
This isn't the first time that Ocean has caught the attention of big name artists. The 23-year-old has previously worked with the likes of Justin Bieber, John Legend and Brandy. He is also rumored to have worked with Beyonce.
