Britney Spears leaving the west village boutique in London (6/18)

According to the Daily Mail, fans were left "stunned" last night when Britney Spears kicked off her show in Manchester, England, by yelling 'What's up London?'. Oh the horror! From the newspaper:

Whatever the reason for her confusion, concertgoers were less than impressed with the 27-year-old singer's slip -up.

"If she can't tell the difference between London and Manchester what hope has she got?" asked a mother who took her 14-year-old daughter to the show.

This mom realizes that this is the same woman that kidnapped her kids and held them hostage a year ago, right? I think we can forgive a little slip up about forgetting where she was. Besides, being confused with a world class city like London isn't exactly the worse thing in the world. It's not like she confused it with somewhere really embarrassing like Florida.
