Apparently Britney Spears’ dance routines are getting to her, and they’re causing her trouble with her Circus tour.

Rumor has it that she’s unable to keep up and is struggling with her dance routines, or she’s pregnant.

A source claims that Britney is “feeling dizzy, nauseous, and even losing clumps of her hair.” While the first two sound like pregnancy or just plain exhaustion, the last one makes it sound like she has cancer.

The source adds, “The choreography is insane – it’s so fast it is really taking its toll on her. There is one move during ‘Touch Of My Hand’, where two guys dangle from the ceiling and pick her up upside down, which is really getting to her. She spins around for nearly five minutes some nights. The blood rushes to her head and when she gets down she complains of nausea and dizziness. There have been a couple of times when she ran off the stage and vomited.”

Is this a lot of hoopla? Or is there something else at work here?
