Zac Efron Was on a Six-Week Liquid Food Diet After Breaking His Jaw: "I Lost Like 10-12 Pounds!"

"It was pretty gnarly," the star of That Awkward Moment says of his accidental injury

If Zac Efron seemed slimmer during his That Awkward Moment press tour, it's because he was.

The 26-year-old actor revealed that an accidental injury led to unexpected weight loss during a Thursday, Jan. 30, appearance on ABC's Jimmy Kimmel Live. "I actually broke my jaw," Efron said, confirming E! News' exclusive scoop from November 2013. "I was running through my house and I slipped and fell on my face."

"Let me start over, because the story starts kind of cool," the movie star continued. "I have a fountain in my house. That's kind of dope, right? So I was running through and slipped on water and hit my chin on the fountain in my house. It's not a big fountain, but it's a fountain in my house."

Efron's younger brother took him to the hospital, where the actor got his "jaw wired shut" for a month and a half. "It was pretty gnarly," the single star said. "I was drinking foods solidly for six weeks—only liquid foods. It sucked...I lost, like, 10-12 pounds."

The actor, who completed a stint in rehab in 2013, is feeling great. "I'm in the best place I've ever been. I've never been this happy before," he said during a Jan. 21 Today interview. "Things are good."
