Do blondes have more fun? Adam Levine is about to find out.

The singer and The Voice star surprised fans with a casual photo of himself and fiancé Behati Prinsloo in the bathroom mirror. "Apocalypse prep course complete," he wrote alongside the shot.

It’s pretty courageous for Levine to use his phone again, after fellow Voice coach Blake Shelton revealed his personal phone number to a national audience last week. Shelton posted the number to the show’s website, which caused Levine to say, "Are you kidding me? That is not funny... Just know that you have it coming because that's not cool at all."

By the end of the episode, Shelton was given Levine's phone to answer calls from fans. "This is Blake. I'm answering Adam's phone because I actually feel bad that I gave his number out. So, I'm answering the phone now," he was shown saying on the phone.
