British boyband The Wanted have lifted the lid on Britney Spears' diva demands, just days after they branded her rival Christina Aguilera "rude".

The Glad You Came singers were left disappointed after meeting Aguilera backstage on US TV talent show The Voice in April, when the Beautiful singer allegedly refused to speak to them.

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

The singer has now turned on Aguilera's former The Mickey Mouse Club co-star Spears, claiming the Toxic superstar's minders made the band face the wall as she walked past them backstage when they supported her during the UK leg of her world tour in 2011.

Parker tells New York radio station Fresh 102.7, "We signed a confidentiality thing that we should never say anything about what happened, but let's tell it anyway."

Bandmate Siva Kaneswaran adds, "I was in the hallway with my tour manager. Basically we were looking with a laptop, trying to get WiFi ... facing the middle of the hallway. (Britney's) bouncers came down with her and told us to face the wall ... As Miss Spears is walking through. 'We're like, come on!'

"We turned around and I faced a wall for about 10 seconds until she got really far away."

According to PerezHilton.com once the members of The Wanted were able to meet Spears without her minders, she was more receptive.

Jay McGuinness saying “when we actually met her person to person, she was so down to earth. You can tell she’s a total southern girl and Nathan, when he was a kid, won a singing competition. She was one of the judges or something. And she gave him a kiss, it was one of his first kisses as a kid. So he got to meet her again and support her.”
