The Wanted claim: We were told to face the wall when Britney Spears came down the corridor
The boys say they were backstage trying to find Wi-Fi in the hallway before opening a concert with Britney, 30, when the diva-like incident happened.
'Britney's bouncers came down with her and told us to face the wall,' says Siva Kaneswaran, 23.
'We turned around and I faced the wall for about 10 seconds until she got really far away.'
The band later seemed to regret bad-mouthing Christina - and perhaps they should've also kept their mouths shut on this occasion.
'We signed a confidentiality thing that we should never say anything about what happened,' Tom Parker, 23, told New York's Fresh 102.7.
'But let's tell it anyway.'
Britney's spokesman says the claims are 'false'.
