On Wednesday, the 43-year-old actor took to Twitter to share a workout selfie, which showcased a bright blue mohawk.
“Time to go to work…,” he captioned the picture.
Fans, including Manganiello’s famous pals, couldn’t help but comment on the transformation.
“YOU DYED IT BLUE?!?!?!” asked Jesse Tyler Ferguson, who starred in “Modern Family” with Manganiello’s wife, Sofia Vergara.
Just last month, Manganiello showed off another hairstyle: a blonde mohawk.
In the picture, his hair was on full display as he sat on a couch, holding one of his pups in his arms. “G’night,” he captioned the snapshot.
