Britney Spears performing at the O2 Arena in London (6/3)

Britney Spears kicked off the European leg of her Circus tour last night in London. She'll be performing eight concerts in the city over the next week-and-a-half, which means eight parties in which she'll be dancing with midgets and topless chicks. Wait, what? From Yahoo!:

Britney Spears is planning a week of raunchy London parties. The 'Womanizer' singer - who kicks off the UK leg of her 'Circus' tour at the city's O2 arena ... has hired naked acrobats, topless burlesque performers and dancing dwarves to perform after each of her eight shows. Minutes after the 27-year-old star finishes her last racy number, Club Dada will open at the arena's indig02 venue. By the time Britney arrives, the party is expected to be in full swing, and is likely to continue until the early hours of the morning.

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."

Naked acrobats? Topless women? Dancing midgets? It sounds like Britney's either throwing one hell of a party or VH1's filming their next episode of Charm School. If Britney ever wants to gain back control of her estate from her dad, she's gonna have a hard time convincing a judge she's mentally stable after these parties. She'd probably be better off dressing up like a clown and completely humiliating herself -- i.e. what Lady Gaga does in public on a near daily basis. [WENN]
