Have you ever been jealous that your best friend got something you wanted?  That car you've been lusting over, maybe a date with that girl/guy that you were crushing on, possibly a job?  The Express reports the Dynamic Duo that is Ben Affleck and Matt Damon has been shaken by that greed-eyed villain - envy (you were thinking Poison Ivy?).

Why?  According to Affleck, it's because Matt Damon is jealous of Ben's role as the Dark Knight.  The Batman is rumored for a 2018 release (likely Oct. 5th), and will pit Affleck's Batman against Joe Manganiello's Deathstroke.

Both of these guys have been super-successful in Hollywood, and have been famously friends since before they made it big.  The pair famously hit it big when they co-wrote and won the Best Screenwriting Oscar for Good Will Hunting in 1997 during their mid-twenties.  Naturally, they have been busting each other's chops for years.  According to Ben, “He’s (Damon) very bitter. All he gets to do is Jason Bourne.  (He) Just keeps doing it again and again. We get it."
