Zac tried to give Details magazine as much detail during his cover shoot interview without getting too gross.

During his interview, Zac was suffering from "a bad case of poison oak" that he got while hiking with friends in a California park.

“Dude, it’s like everywhere. Everywhere. I can’t even begin to show you, ‘cause you’ll get so grossed out," he tells Details. "I look like a zombie from Dawn of the Dead.”

But Zac doesn't usually have the problem of looking bad, in fact, most times he looks too good!

Adam Shankman, the director of Hairspray, had to tell Zac to stop smiling so much.

"It's not how I am," Zac says. "Even in my audition I was smiling and happy. Not cool."

In a way, Zac wishes he could be more like Shia LaBeouf, who can seem to say anything and not damage his career.

"I'm so jealous of that," Zac says of Shia, whom he doesn't know personally. "Yeah, that's awesome to not give a s**t. And Shia still pulls it off. That's so cool. It's just awesome. It just comes easy to some people."
