Britney Spears will be sawn in half as part of her upcoming stage show.

The 27-year-old singer will be a magician's assistant during her 'Circus' tour - which kicks off in March - working with 'Misfit of Magic' illusionist-and-comedian Ed Alonzo.

Ed said: "Right away, she got into the boxes and into the magic contraptions to learn the stuff, and she's so excited about this tour and all the elements that are in it. We're going to be doing the classics of magic but a little high-tech. We'll be doing a little dissection, transposition, a vanish and an appearance."

Ed has specially developed each trick and says Britney will have to put her body on the line for several difficult sequences.

He added: "If I do a trick, she doesn't just hold the props, she's actually getting inside the big boxes or I am slicing her up.

"I made the tricks really easy for her, but there are some complicated things that she is doing that you would think a contortionist would have to do, or a trained magician's assistant. But because she's a dancer, it really makes sense to put her in the magic, and it works and she's really, really good at it."

Ed refused to reveal which of Britney's songs will accompany their appearance together, but did reveal the three-ring circus set for the concerts will amaze fans.

He told 'E!' News: "It's like watching a big Cirque du Soleil high-tech circus, but with a really focused star in the middle of all of this. It's going to be an amazing concert for people to watch."

Meanwhile, Britney's ex-boyfriend Adnan Ghalib is facing three felony charges - assault with a deadly weapon, hit-and-run and battery - over claims he drove his Mercedes at an unnamed victim.

It is alleged the victim was serving Adnan with a temporary restraining from Britney's father Jamie, at the time of the incident.

If convicted, Adnan faces up to seven years in prison.
