Mark Wahlberg, 49, debuted his boxer to priest body transformation for his latest movie role in side-by-side photos on May 3. In the left photo, we see Mark packing a chiseled six-pack while flexing in a pair of Everlast boxing shorts. The photo on the right, though, showed a much different (and much more relatable) image after the actor gained 20 pounds: Mark laying in bed with a relaxed tum.
