In only took Mark Wahlberg three weeks to completely transform his body. Wahlberg shared his new look in a picture posted on Instagram. So far he's up 20 lbs for his new role in the upcoming movie, Father Stu, where he plays the role of a boxer turned - priest. The before and after shot shows Wahlberg going from a rock solid stomach to an over night "Dad bod." Regardless of what size this man is.... he's gorgeous in all shapes.
