LATEST: Actor John Cusack is slamming reports he isn't supportive of longtime friend Jeremy Piven's recent career successes. Piven was quoted in America's Best Life magazine saying the pair had a falling out after Cusack became jealous of his new found fame. Piven had played supporting roles in many of Cusack's films, including SAY ANYTHING, Grosse Pointe Blank and Runaway Jury, before landing a role on the hit series ENTOURAGE, for which he won an Emmy Award last year (06). Cusack hits back at the claims he isn't thrilled about his friend's success telling American publication People, "It's quite the contrary. I am very happy for Jeremy. I wish him the best and always have." The pair first studied acting together at Chicago's Piven Theatre Workshop in Illinois, which was run by Piven's parents.
