The pop star is the new face of Popchips and will appear in advertising for the brand this fall.
"I was hooked after my first bite!" Perry said in a release. "When I discover something good, I want to share it with everyone I know, so I tweeted about it."
Popchips approached her, and the rest is history. Perry will also be investing in the company and becoming a creative partner, joining fellow Popchips celeb investors such as Ashton Kutcher, David Ortiz and Sean "Diddy" Combs.
It won't be Perry's first venture into the business world: she's lent her name to two fragrances and partnered with brands such as Ubisoft, as well as serving as producer on her recent concert film, "Katy Perry: Part of Me."
