This really hasn't been Zac Efron's year!

After going to rehab twice for alleged addictions to alcohol and cocaine, Efron broke his jaw after slipping on a puddle of water at the entrance to his Los Angeles home on Sunday. The 26-year-old star's jaw has been wired shut, and E! Online reports that the actor also suffered a gash that required stitches.

While Efron is expected to make a full recovery, his appearances to promote his upcoming movie That Awkward Moment have been put on hold.

Efron initially sought treatment in March for substance abuse issues, but after having a relapse, he went back to an undisclosed rehab center to get clean yet again. After taking a trip to Peru with his father in September, Zac has been maintaining a low profile, but last month he had a mellow evening out with former Hairspray co-star Brittany Snow, along with Julianne and Derek Hough at the Los Angeles Haunted Hayride. It sounds like he's getting back on track, so hopefully he feels better soon!
