Katy Perry Plays Mermaid in New Hair Ad

Katy Perry rivaled the watery grace of Ariel when she transformed into a mermaid for her new ad campaign for ghd hair straighteners. Shot by renowned photographer David LaChapelle, the ad (seen above) spotlights Perry's gorgeous lavender locks.

"David La Chapelle made the set amazing," she told Marie Claire. "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 "Firework" singer also admitted that she was "such a fan of the Disney movies," and is considering keeping the mermaid costume as an option for next Halloween.

Mermaids seem to be all the rage in the pop world right now. Is anyone else thinking of Yuyi, Lady Gaga's mythical sea creature alter from her "You and I" video? Which pop diva do you think made a bigger splash as a Mermaid?
