Dan Haren secretly filmed Jered Weaver dancing at a J. Lo concert on Friday night

Since retiring at the end of the 2015 season, Dan Haren has seemingly made it his personal mission to pull the veil back behind a Major Leaguer's life, like his Twitter account was the sporting equivalent of "Magic's Biggest Secrets Finally Revealed." 
He's let everyone know his gastronomical needs before a start and then showed why everyone wants to be a retired ballplayer: Because you can play Legend of Zelda all day long.  
Now, like a Gonzo journalist, he's gone undercover at a J. Lo concert to capture Jered Weaver grooving to the pop beats. 

The very best part of this is when Weaver reaches for the camera like it's the end of a found footage horror film. Which means it's now time to hope for a sequel.
