Mark Wahlberg isn’t all guns and muscles anymore!

His upcoming motion picture, titled ‘Father Stu’, focuses on a boxer-turned-priest and calls for Walberg to gain weight in order to play the part.  His time partnering up with Christian Bale on the set of ‘The Fighter’ seemed to have payed off when he revealed his staggering body transformation with a before-and-after update on Instagram to his 16.3 Million followers, along with the caption “From this 3 weeks ago, to this, now.” 

When opening up about his regiment for the makeover, he said he wanted to “eat everything in sight”!
