On Saturday night (April 4th), rapper Big Sean surprised guests with a surprise performance at Bounce Sporting Club to celebrate the final four championship NCAA games. In between the Duke vs. Michigan State and Wisconsin vs. Kentucky game, Big Sean rapped some of his new songs, and after posed with fans. An attendee said that he didn’t turn down one fan photo opportunity and was a completely nice and genuine guy. Big Sean was rocking a sweatshirt for his new collaboration with Bape, which will be launching next month.
