The Wanted: Christina Aguilera is a 'total bitch'

The Wanted have branded Christina Aguilera a "total bitch".

The Glad You Came hitmakers claim the 31-year-old singer was "scary" and refused to talk to them when they met her backstage at US talent show The Voice.

Singer Tom Parker told Now FM: "She's a total bitch! She might not be a bitch in real life but to us she was a bitch. She just sat there and didn't speak to us."

Bandmate Max George added: "She was a bit scary to be honest."

Siva Kaneswara said: "You know what, she was quite rude."

The boy band - completed by Nathan Sykes - claimed The Voice USA panellist even shunned Justin Bieber when he attempted to embrace her.

Nathan said: "She might have been in a bad mood that day - didn't she completely par Justin Bieber as well? He went in for a hug and she was like, 'Get away from me'."

Max kissed Jennifer Lopez following The Wanted's performance of Glad You Came on American Idol earlier this month, and when comparing the On The Floor hitmaker with Christina, he insisted the blonde singer is "nothing special".

He explained: "J Lo is hot you know, Christina's nothing special."
