And now we know how he transformed his bod, he runs every morning in Malibu!!
We don't remember the Gangster Squad actor EVER looking like this, but apparently the air in the beachfront city is treating him right.
Now if only Sean would let us move into his lavish home in Malibu… so we can look just like him! LOLz
Ch-ch-check out the handsome hunk getting his run on (above)!
