Last fall, pop star Katy Perry dressed up like a geisha for her performance at the American Music Awards, and was quickly accused of being racially insensitive.

Now the singer is back in the spotlight for the same reason, this time for the "dancing mummies" seen onstage at her latest show in London. The mummies have huge breasts and butts, as well as having big, plastic red lips.

Many viewed the use of the dancers as racist and took Katy to task via Twitter over the costumes. Peep some of the outrage above.

Were these costumes inappropriate or are people overreacting? Sound off below.
