Zac Efron arrives at the 75th Annual Golden Globe Awards at The Beverly Hilton Hotel on Jan. 7, 2018 in Beverly Hills, Calif.
Throughout his career, Zac Efron has frequently switched up his facial-hair game -- going from clean-shaven to full beard with mustache and everything in between.
But on Friday (March 30), the actor took things to a whole new level with an #FBF photo posted to Instagram.
In the up-close shot, Efron sports a striped beard, while his hair is styled in an undercut with blond sides. The 30-year-old simply captioned the photo "beast mode."
Although the photo left fans wondering when he’d debut the beard, Business Insider previously reported that the look was for Efron's upcoming role in the film The Beach Bum.
Here are a few of our favorite fan reactions to the star’s most recent Instagram selfie -- which many likened to a "panini press" pattern.
