Mark Wahlberg, 49, turned heads on May 21 while playing the part of Father Stuart Long on the set of his upcoming film Stu. The actor transformed into the boxer-turned priest by parting ways with his usually toned physique and taking on natural weight gain as well as a fat suit and prosthetics. He was photographed showing off a chin prosthetic and wearing the big suit while smiling and roaming around the L.A. filming location.
