Just when things were looking up
for Zac Efron
, the handsome actor suffered another setback.
The recently rehabbed Parkland
star, 26, broke his jaw on Sunday at his Los Angeles-area home, a source confirms to PEOPLE.
The insider also confirms that Efron, who slipped on a puddle, has his mouth wired shut and received stitches from a gash he suffered. Plans to promote upcoming film That Awkward Moment
have been postponed.
Efron seemed in good spirits
in the last month, when he celebrated his birthday with some golf in Carlsbad, Calif., and joined Moment costar Michael B. Jordan
at a Vanity Fair
was the first to report the story. Reporting by JULIE JORDAN
