Gym, tan, furlough! Mike “The Situation” Sorrentino, 36, is being treated like a king during his prison stint in Otisville, N.Y., a source tells Life & Style — and it’s all down to his status as an Italian stallion. “There’s a new correctional offcer, and word is he and Mike have bonded over their shared heritage, ” dishes the insider.
