Jay Z was out in full force with a crew of celebs including, Drake, Wale, and Victor Cruz. Information is sparse on why they were all out together, but the "Started from the Bottom" rapper had just wrapped up an interview with Rap Radar CEO Elliot Wilson earlier in the evening. 

During the interview, Drake revealed that "Pound Cake" was originally intended for Jay's "Magna Carta" album, but he later asked for it back and the song transformed into what you hear on Drake's new album. Check out the photo of Jay hanging with everyone in the above slide:
