(Yahoo!) - Adam Levine looks like he's taking style notes from his new "The Voice" co-star Gwen Stefani.

The 35-year-old musician (and reigning Sexiest Man Alive according to People) dyed his dark locks platinum blond, which is nearly the same color as the No Doubt singer's signature 'do. Levine revealed his extreme new style in a snapshot on Twitter on Saturday.

"Apocalypse prep course complete," he succinctly captioned the shot.

Also ready for the apocalypse in the pic is Levine's fiancée, Behati Prinsloo. It appears that the Victoria's Secret Angel changed up her hair a bit as well, trading her ombre highlights for a steady brunette shade.
