Singer feels side effects of dance routines

Britney Spears is reportedly struggling with her rigorous dance moves on her Circus tour.

The singer, 27, is said to have been feeling sick when she comes off stage.

‘The choreography is insane – it’s so fast it is really taking its toll on her,’ a source tells the Daily Mirror. 

‘But there is one move during Touch Of My Hand, where two of the 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 stage and vomited. It’s not a pretty sight.’

Britney is now planning to tone down some of the routines.
