Beverly McClellan recently did an exclusive interview with Yahoo!, she mentioned about Christina.

“When (Christina Aguilera) and Adam (Levine) turned around, I thought, if anybody has anything to teach me, it’s going to be Christina. I did the right thing — I found out we had Etta James in common, so that made me very happy. And that’s something we didn’t know when she turned around.”

Aguilera was obviously a fan of McClellan, as well, who ended up being the singer representing her team in the finals. If McClellan had to sum up her feelings about the musical diva in one sentence, she has no problem hitting in on the head.

“She’s lipstick on fire is what she is,” McClellan laughs. “With perfect pitch.”

And speaking of fire, if there was one thing she could have done differently on “The Voice,” she can tell you exactly what it would have been, without the slightest hesitation.

“I might have set the piano on fire. I asked them to do that but they said no. It was one of four in the world, so instead I laid on it. They told me not to do that, too. But hey, it’s live television, what are you gonna do? Don’t tell me not to do something, cause that’s the first thing I’m gonna do.”
