The Wanted: "Christina Aguilera's a b****!"

They've always been known as a boyband who speak their minds, but those cheeky chaps from The Wanted have gone one further this week, branding singing diva Christina Aguilera a b*tch!

Christina, current judge on The Voice USA, is said to have blanked the lads when they appeared on the show after they tried to speak with her backstage. Max George deemed the star as "a bit scary to be honest", but then fellow band member Tom Parker angrily waded in, adding,

"She's a total b*tch! She might not be a bi*ch in real life but to us she was a b*tch. She just sat there and didn't speak to us."

Singer Nathan Sykes then added that Christina is said to have been frosty towards another pop sensation, teeny bopper Justin Bieber. Nathan revealed,

"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',"

The Wanted have been accross the pond trying to make it in the US, they must feel nervous after seeing One Direction's rapid rise to fame in the American charts.

However, it's not all hard work, Max definitely had something to smile about after a cheeky kiss from American Idol judge Jennifer Lopez. He used his anecdote in a further put down to Christina, saying,

"J Lo is hot you know, Christina's nothing special." Ouch.

We wonder what Christina has to say about all of this?
