“Zac was in Charlie’s inner circle for a few months earlier this year. The two became very good friends. Zac was spending a lot of time at Charlie’s Beverly Hills mansion and they were definitely partying together, sometimes for days at at time."
During the times they would hang, Zefron even visited the Anger Management set to chill with the 48-year-old star:
“Zac visited Charlie on the set of Anger Management at least a dozen times,” the insider said. “The two would hole up in Charlie’s trailer when he wasn’t filming.”
Soon after his tryst with Mr. Sheen, Zac disappeared, assuming he was in rehab to cope with his addiction.
