Britney Spears is not smart.

Once again, the singer gave a city the wrong shout-out, this time in the UK, where she opened up her show in Manchester with a nice “What’s up London?!”

Hey, as long as she has her stripper pole in the hotel and remembers her meds so she doesn't shave her head and go topless, it makes litle difference:

Britney: What's Up London!

The best part of the above clip? The crowd going wild despite not actually being in London. Who cares if she has no idea where she is - Britney Spears spoke to them!

Rumor has it then when someone pointed out the error to the singer later, she giggled and just said ding dang, she’s not very good at geology y'all.

Just kidding. Mostly.

Britney Spears previously mixed up Sacramento and San Jose, which is a bit more understandable, given the whirlwind nature of her U.S. tour at the time.

Either way, just be glad she didn't have a wardrobe malfunction. Or tell motherf*%kers to rock out with their c*cks out. Or make any references to her pu$$y.
