‘The Wanted' were guests on the April 13th episode of ‘The Voice', and during an interview with a radio station this morning they were asked what that was like. You probably got the gist of their response from the headline. Vulture says:
(They were) asked about their recent 'Voice' appearance and let go on Christina Aguilera. "She's a bitch!" Tom Parker yells three or four times. Then Siva confirms that she was "quite rude," and Max spends a little while talking about how much hotter J. Lo is when compared to Christina.
Luckily for them, the Eskimo Pie factory wasn't playing this station on their radio so Christina didn't hear it.
