Is This Katy Perry Or A Mermaid?

She look almost unrecognisable in a new ad for her new campaign GHD Air hair dryers, in which she was styled like a Mermaid.

According to celebdirtylaundry.com:

Katy Perry said this about the shoot:

"David LaChapelle made the set amazing, it was fun – I got to have purple hair which foreshadowed the real purple hair I had last fall. It's as if Lisa Frank had done The Little Mermaid."

The Little Mermaid indeed – and who wouldn't want to be a mermaid for a day? GHD dryers promise "the best results of any hair dryer on the market."
