"The Voice" judge bleached his locks platinum blonde, trading in his signature brown hair for a much lighter hue.
The Maroon 5 frontman shared a snapshot of his new look on Twitter writing, "Apocalypse prep course complete."
Adam's fiance Behati Prinsloo must approve of the change, as she was posing with him in the mirror selfie.
The musician is no stranger to changing up his 'do. Last month he debuted a half-shaved, half-clipped and fully gelled hairstyle on the red carpet at "The Voice's" season 6 private concert in Los Angeles.
Levine's stylist Shaul Arbiv tells People the 35-year-old was ready for another change.
"With summer months coming up we wanted to do something totally drastic and different from his previous styles so we bleached it," Arbiv said. "I have been working with Adam for a long time and he likes to change up his style often."
