Pauly D is serving up a 6-pack in Mexico and we've learned his svelte physique partially thanks to GTL ... Gym, Tan, Lipo.
The "Jersey Shore: Family Vacation" star has been in Cancún with co-star, Vinny Guadigno, as the two host events for the revival of MTV's Spring Break.
During a Thursday beach session, the reality star DJ was showing off his abs, which sources close to the star tell us, is the result of an abdominal etching treatment he recently received.
Pauly does deserve credit for his muscular look, as abdominal muscles are needed to help produce the best result. The process accentuates existing muscle by removing fat around the muscles, which produces the coveted washboard.
Gotta admit, he looks great.
