It seems old habits may die hard for Zac Efron. A witness tells In Touch that the High School Musical star, 27 — who entered rehab twice in 2013 for an alleged cocaine addiction — was acting suspiciously at the Treats Halloween Party in LA on Oct. 31.
“Zac, his girlfriend [model Sami Miró] and another male all entered the men’s bathroom together and ducked into one small toilet stall,” says the witness, adding that “the sound of noses sniffing” could be heard from inside the stall. “A few minutes later, they all emerged, quickly exited the bathroom and returned to the VIP area. It was very strange.” (Yeah, strange is one word for it!) “Zac was super drunk at the party,” says a witness.
