Britney Spears is reportedly so worried about damaging her voice that she intends to have regular sessions in a £15,000 oxygen chamber Michael Jackson-style, its claimed.

The move reportedly comes after the singer halted a show on her Circus tour last month, complaining that the air in the venue was too smoky.

A source tells The Sun: “Since her Vancouver gig, where she ran off stage as it was too smoky, she’s become paranoid about breathing in too much bad air.

“She’s keen on an oxygen chamber that will reverse any smoke inhalation damage."

Why bother? It's not as if Britney needs her voice to 'sing'?
