Chris Rock -- Holds Court with HUGE Stars ... But Who's the Biggest Baller?!

Interesting celebrity foursome at the Knicks vs. 76ers game Wednesday night -- Chris Rock, Beastie Boys rapper Adam Horovitz, Ben Stiller and Jimmy Fallon.

Huge stars ... super successful ... and it got us thinking -- who's got the biggest bank account?

Chris Rock -- movies, syndicated TV show, stand-up ... dude's ballin'

Ad-Rock -- 33 huge years as hip-hop royalty

Ben Stiller -- movies, movies, movies, movies

Jimmy Fallon -- talk show money is no joke

Bottom line ... we don't really know who's got the most cash -- but if they combined forces, they could probably buy a team ... like the 76ers.
