"I woke up like this," Efron wrote along with a photo of himself getting styled in the green room before his appearance on Jimmy Kimmel Live!, promoting his new film Dirty Grandpa.
It's unclear if Efron means that he sleeps in denim jeans or if he wakes up with a woman running her hand through his hair, but both are possible.
Much of the ad campaign for Dirty Grandpa revolves around Efron being half-naked throughout the movie, so it's not surprising to see he's stripped off his shirt for more free press, but you have to admire those arms.
He's come a long way since his days on High School Musical, which is perhaps why he didn't show up for the show's 10th anniversary reunion on Wednesday. Or maybe Disney wouldn't let him show up topless, and Efron wasn't having it. We may never know.
