The bizarre story about altercation with a homeless man on Skid Row that surfaced this week reportedly have Zac Efron’s friends worried that he has relapsed.

Apparently the story is too far-fetched for them to believe, which only leads them to think he is no longer sober and was in the neighborhood for less juvenile reasons than just going to a sushi restaurant.

One of his friends told TMZ, "Zac's a loner. He goes out rarely and the idea of him driving for miles to go to some sushi restaurant in downtown L.A. after midnight is preposterous."

Sources also say some of his friends have stopped communication with him because they believe he’s using again. Those close to him are also reportedly concerned about the “bodyguard” he’s been spending a lot of time with, considering he has a criminal record.
There are now conflicting reports surfacing about Efron’s two rehab stints for cocaine, with insiders saying he never actually did go to rehab just a friend’s house where he got private counseling.
