DJ Pauly D is getting a new GTL — Guiness, Tullamore and luck of the Irish. The Jersey Shore star will join The Dropkick Murpheys, Carbon Leaf, Scythian and more than 40 other performers at this year’s Shamrockfest at the RFK Stadium Festival Grounds. We’re not sure what about a fist-pumping and a gelled-hair Italian guy screams “St. Patrick’s Day,” but we’re excited to see if he chugs some green beer and dances the Irish jig. ShamrockFest starts at 1 p.m. on Saturday, March 12. Early bird general and VIP tickets are on sale at www.shamrockfest.com.
