Britney Planning Raunchy Concert Parties in London

Britney Spears' Circus is about to get raunchier. The 'Womanizer' is planning on stepping up the sex factor for the UK leg of her 'Circus' tour by hiring naked acrobats, topless burlesque performers and dancing dwarves to perform after each of her eight shows.

Britney's show was already R-rated while in the states, but in the UK, anything goes. And Britney wants to make sure her concert will be talked about for years.

A source said: "It's going to be crazy. Britney wanted to throw parties people will be talking about for years. I promise you, you've never seen anything so explicit in your life."

Just minutes after Britney's done, "Club Dada," will take over and rock the audience. Sounds like a party within a party.

Britney will perform eight London shows between June 3 and 14 before the tour moves onto Manchester, Ireland and France. Have you been to any of her concerts? What are your thoughts about the pop princess' 'Circus' tour?
