In the battle of the U.S. singing competition shows, The Wanted is definitely voting for American Idol.

While appearing on New York radio station 92.3 Now, band member Max George was asked why he gave a kiss to Idol judge Jennifer Lopez and not The Voice's Christina Aguilera  after the group appeared on both shows this year. "She was bit scary, to be honest," George explained.

"She's a total b----," bandmate Tom Parker said. "She might not be a b---- in real life but to us she was a b----. She just sat there and didn't speak to us. Wouldn't even look at us."

A source close to the show told People that Aguilera, 31, did not intend to brush off the pop group, but that time didn't allow for her to say hello. "There was no opportunity for interaction at any point during the show or prior to the show," the source says. "The first time Christina saw them was when she was already seated in her coach's chair and they were performing."
