Drake and Rihanna reunited over dinner at Sons of Essex Friday night. Sources said Drake, who was there with another female pal, arrived at 10 with a group of 10 and sat in back. An hour later, Rihanna came in alone. Spies said Rihanna sat across from Drake, and the group ordered a round of shots. “They were in very good spirits and were dancing and singing. Drake and Rihanna seemed to be just friends enjoying a fun night out.” Fans tried to take photos, but bouncers eventually stopped that. Rihanna and Drake, who collaborated on Drake’s song, “Take Care,” left separately, but the group left a generous $500 tip.
