There's no denying that Shelton and Adam Levine have one of the best bromances on TV. So when ETonline caught up with the coaches after The Voice on Monday, we knew it was time to get the musical BFFs to spill each other's cups and tell the truth.
So what are the coaches really sipping on during all those long hours in their big red chairs? Levine was quick to shut down any alcoholic rumors and revealed that the only thing in his cup is "Coffee, ma'am." He then added, "Blake is a different story, he might want to be the one to tell you."
Shelton was a little bit more forthcoming with what his friend is really hiding behind that Starbucks logo. "Adam has crack that he keeps in his cup," The six-foot-five country star joked. "And he supports that sort of thing.
As for Blake? His answer was short, but candid. "I have vodka. I drink vodka on the show," he spilled. "Now that I think of it, every damn brand of vodka has been in that cup. And I don’t care if you like it or if anybody likes it, that's what I drink so get over it."
Hey, no one is judging you, Blake — we just want you to share!
