(Yahoo!) - Say it ain't so!

Actually, Zac Efron won't be saying much of anything for a while.

A source confirms to omg! that the actor broke his jaw after slipping in an unseen puddle of water in front of his L.A. home on Sunday and had to have his mouth wired shut as a result.

Efron, who will next appear on the big screen next January in "That Awkward Moment," also had to have stitches to mend a gash he received from the fall.

The hunky star has been having a rather rough 2013. In September it was revealed that he completed two stints inrehab earlier this year to battle an alleged cocaine addiction.

However, after going on a trip with his father to Peru, and celebrating his 26th birthday with a low-key party at theChateau Marmont (that boasted not-so-low-key guests like Robert Pattinson and Joe Jonas), the actor had returned to the Hollywood circuit, most recently participating in a "That Awkward Moment" Q&A. He also supported his co-star in the film, Michael B. Jordan, at a Vanity Fair event just last week.

But it looks like all additional promotion for the movie will have to wait until Efron has recovered.

Get well soon Zac!
