Mike' The Situation' Sorrentino has called Fyre Festival co-founder Billy McFarland a "bonehead" following recent controversy over a recording device.

Mike, who did time in the same facility as Billy, recently sat down with friend and Jersey Shore co-star Nicole "Snooki" Polizzi to discuss prison - and he didn't hold back when it came to Billy.

"He supposedly smuggled in some sort of recording device, and he was caught with it," Mike said on the It's Happening with Snooki & Joey podcast. "They said he was trying to record high-profile inmates and they threw him in the SHU [solitary housing unit]. They sent him to a worse prison, I think, recently. That's a bonehead move right there."

He continued, "I don't even know why he'd be recording in there. Maybe he was trying to write a book or something? I don't know."

Nobody should be too shocked by Billy's antics. In a Fyre Festival documentary, Billy was busted for trying to run another scam while the feds were investigating him.
