British R&B singer Jay Sean was spotted tearing up the town on Tuesday night. According to a Yeas & Nays spy, the 30-year-old dined at Lost Society at 14th and U streets NW with friend and Club Eden co-owner Vinoda Basnayake. We're told Sean ordered the filet for his entree and downed Patron Cafe shots with several female fans before he and Basnayake hit up Eden for some late-night fun. Sean is in town while on tour with Joe Jonas.
