Katy Perry: Mermaid for GHD Ads!

Katy Perry poses as a mermaid in this new shot from her campaign for GHD Air hair dryers.

The 26-year-old entertainer posed for celebrity photographer David LaChapelle for the shoot.

“David La Chapelle made the set amazing,” Katy said (via Yahoo!). “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.”

GHD Air hair dryers promise “the best results of any hair dryer on the market.”
