The `Glad You Came` singers claimed that they were subjected to the diva treatment by the star`s team when they were the opening act for her Manchester concert last year.

The group - consisting of Max George, Jay McGuiness, Tom Parker, Siva Kaneswaran and Nathan Sykes - revealed they were not allowed to face her at the `Toxic` performer when she exited her venue changing room.

Tom spoke up during an interview on New York radio station Fresh 102.7.

He admitted: "We signed a confidentiality thing that we should never say anything about what happened, but let`s tell it anyway."

Siva said: "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."

Tom continued: "As Miss Spears is walking through. We`re like, come on!"

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