All's fair in reality singing competitions and war.

In a recent interview with People, Adam Levine discussed the process the judges go through on The Voice when they are passionate about a particular contestant.

About himself he said, "If I'm going to cry if I don't get someone, if I'm going to freak out, then I'll eventually get that person."

More interesting though was Adam's description of new judge Shakira's tell when she really wants a contestant.

"Shakira's great because you can tell when she wants someone because she starts to sweat and gets hot flashes."

Adam went on to say that he's looking forward to doing battle with Shakira because he's no stranger to "fighting with fiesty blondes."

No word on whether or not Blake Shelton also gets hot flashes during the show though.
