Anyone who watches The Voice knows that co-hosts Adam Levine and Blake Shelton have a bromantic rivalry that often makes the show great.

We think Adam knew exactly what he was getting himself into when he posted a photo showing off his shiny, pink new hairdo, with this caption: "Man up. Go pink. Hair AND Bathrobe.

Man up. Go pink. Hair AND Bathrobe.

Blake wasted no time at all in slamming his friend with hysterical jabs like this one:

And we've never seen unicorn poop before, but we are completely certain Adam is much, much prettier:

Blake wasn't finished yet. Are you kidding? He was just warming up!

He simply couldn't resist this one, and it made us LOL:

Adam debuted his bold hair statement on the knockout episode of "The Voice." Miley Cyrus also appeared on the same show as a key adviser, but with a calmer, more toned down appearance. Maybe she got word that it was Adam's night to shine and didn't want to steal any attention.

Of course, we all know that Adam and Blake, known as "Bladam" in some circles, are really besties. Blake once explained their dynamic to Rolling Stone:

"It's so foreign to see anything that's genuine on television these days," he explained. "That's why I think so much attention is focused on Adam and I.

Blake continued, "You can tell we really like each other. We really are friends, and we're giving each other crap like we've known each other all our lives. I just think the world of that dude."

We can tell, Blake. We can tell.
