Katy Perry goes Old Hollywood glam in the latest campaign images for GHD, a line of hair products and tools. These images are more glamorous and sophisticated than previous campaigns, but Perry looks just as gorgeous. Her hair is like a diamond in the light, since it's so rich and luxe.

The California Gurl was shot by Ellen von Unwerth, while celeb stylist Danilo did her hair. The result is nothing short of stunning. Perry's shiny black locks glimmer with sheen in these black and white shots.

She's smoldering and sultry in the image with the megaphone. Her waves are full and bold, again a stark contrast to the asymmetrical, stick straight teal bob or the dark purple waves she showed us earlier this year when she was in her change-my-hair-weekly phase right around the time of her split with Russell Brand.

She pairs her full, thick curls with a low-back, sequined gown, while peering suggestively over her shoulder. It's one of the sultriest, most grown up images of Perry we've ever seen. No cupcake tops or candy skirts here.

GHD isn't Perry's only endorsement. She is also repping Popchips. Only Perry can pull off endorsing hair tools and healthy snacks. That's why we love her.

Perry's previous GHD campaigns featured her as a pink-haired, punky mermaid and as a smart, sexy gal, playing chess while sporting heavy, youthful bangs.
