We hear that the singer Jay Sean was in town Wednesday night to celebrate the birthday of his buddy businessman Kunal Shah, who co-owns the Eden nightclub and Erwin Gomez's new salon Karma. Jay Sean joined a group of 10 at 901 restaurant and ordered three rounds of tequila shots for the group. He then headed over to the new club Capitale and enjoyed bottles of Moet & Chandon with some ladies, before singing along to his hit song "Down."
