Don't get on the wrong side of those boys from The Wanted - they have taken aim at Britney Spears just days after calling out Christina Aguilera for being ignorant and rude.

They claim the Toxic singer's bouncers ordered them to face the wall when the singer walked past them backstage at the Manchester show they opened for her on tour last year.

Tell-all Tom reveals: "We signed a confidentiality thing that we should never say anything about what happened, but let's tell it anyway."

Siva Kaneswaran took over, adding: "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."

The revelation comes days after the pop hunks revealed they were left unimpressed by Christina Aguilera when they met her backstage on the US version of The Voice, and they later spoke out against the star during a radio interview on Now FM in New York branding her a "total b**ch".

Max George said Christina completely ignored them, adding: "She was a bit scary to be honest."

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