Did Christina Aguilera
pull a diva act on The Wanted?
That's what the boy band is saying after they came away from an appearance on The Voice
feeling most unwanted by the superstar judge.
"She's a total b––––," band member Tom Parker tells 92.3 Now
radio station in New York. "She just sat there and didn't speak to us. Wouldn't even look at us."
Bandmate Max George called the songstress "a bit scary" and "quite rude."
But a source who was on set when the band performed last week denies that Aguilera, 31, purposely gave them the cold shoulder.
"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."
