Katy Perry's hair is her own and appears to be fading to a mixture of bleach blonde ends and brunette roots. Given Katy's penchant for cartoonish and bright stage costumes it always strikes us as odd that she didn't go for full-on hot pink when she decided to dye her hair.
Nicky's is from her apparently endless wig wardrobe (wig-drobe?) and involves a blunt fringe and loose blonde-tipped ringlet curls.
The similarities didn't end with the hairstyles though as the ladies were both rocking some figure-hugging frocks. Katy matched her full-length gown to her hair while Nicky went short, tight and pale blue.
What do you think of the rose-tinted singers?
