With their being lots of alcohol at the Oscars Zac Efron decided to bring his sober coach along with him so he doesn't fall of the wagon.
The actor has been in rehab twice in his 26 years of life and he clearly doesn't want a third.
A source has reported:
Zac has been sober from alcohol and drugs for eight months now and his doing really well.
Brining his sober coach was decently the right move.
