Longtime viewers of "It's Always Sunny in Philadelphia" are well aware of the (one-sided) bromance between Mac and Chase Utley.
Utley even went so far and attempted to break the internet back in 2013 by responding to Mac's love letter.
But today things have gone full circle. Now Utley has a mancrush on Mac, via Chase's own Instagram account.

As you can see, Fat Mac is no longer. There is only Jacked Mac now. Utley is clearly impressed.
In partnership with NBC Sports Philadelphia
Utley and Rob McElhenney have teamed up before to pump up Eagles fans for the Super Bowl.
Chase isn't the only athlete with Philly ties to get in on the Fat Mac content lately. Fat Mac was actually played by an "actor."
