Looks like someone has been working out their glamour muscles, their core and every other body part, because Mac is beyond RIPPED.
Rob McElhenney, who stars on "It's Always Sunny in Philadelphia," popped off his shirt to reveal he's finally become the muscle-bound freak his character has always wanted to be.
Mac was joined by wife and co-star Kaitlin Olson, as well as Danny DeVito and the rest of the "Always Sunny" crew at the L.A. Pride Parade over the weekend. McElhenney looked nearly unrecognizable as he and cast danced atop a Paddy's Pub-themed float.
McElhenney's physique is a far cry from his previous version of "Fat Mac" after he spent five months packing on over 50 lbs of weight because he thought it would be funny.
