JEREMY PIVEN just flipped his freakin’ WIG (literally!) at “Entourage” co-star ADRIAN GRENIER – raging in a face-to-face screamfest that he hates him for giggling to gossipy pals that “Ari” wears a HAIRPIECE!
(We called Piven’s PR peeps who not only denied the battle but insist Piven’s pate ain’t bald.)
Said our source: “It’s a rule among ‘Entourage’ insiders, who know about Piven’s toupee, to never divulge a word because he’s ultra-sensitive about it.
"When confronted, Adrian denied he’d said anything … but Piven ranted that he’s heard it from a bunch of folks, who claim Adrian’s even making jokes about it. The two literally screamed in each other’s faces for a good ten minutes!”
Stay glued.
