Sylvester Stallone announced on Twitter today that Bruce Willis will not be in the next Expendables film, but rather than keeping it strictly business, he totally slammed his fellow action star!

Stallone tweeted, "WILLIS OUT… HARRISON FORD IN !!!! GREAT NEWS !!!!! Been waiting years for this!!!! ... GREEDY AND LAZY …… A SURE FORMULA FOR CAREER FAILURE." (Stallone's rep later confirmed that the tweet was in fact about Willis.)

Willis appeared in the first two Expendables films, both of which Stallone co-wrote. Stallone directed Willis in the first film, but this is honestly the first we've heard of the Hollywood heavyweights butting heads! Heck, we even snapped photos of Sly and Bruce and their lady loves out to dinner a little over a year ago ... wonder what went wrong?

Production for The Expendables 3 is scheduled to begin later this month, and the film is expected to hit theaters on November 15, 2014.
