Britney Spears Needs Some Air

Britney Spears is taking unusual steps to keep herself in top performing shape on her Circus tour.

First the “Womanizer” warbler requested a stripper pole for her hotel suite during her upcoming run of London shows so she can exercise between gigs.

Now, British newspaper the Sun reports, she plans to drop about $22,000 on an oxygen chamber to replenish her lungs.

Spears briefly halted a concert in Vancouver last month because she’d felt the arena had become too smoky. And now, apparently, she’s found a way to counteract the effects of inconsiderate, ciggie-puffing audience members.

“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,” a source reveals to the paper. “She’s keen on an oxygen chamber that will reverse any smoke inhalation damage.”

Smart move, Brit-Brit. Plus, that extra oxygen will come in handy if you have to make a run for it, should another crazed fan decide to rush the stage.
