Katy and Nicky are even clutching the microphone the same way. Photo:PA
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?
