Katy Perry has become an ambassador for Popchips as well as investing in the snack brand.

The brand partnership was apparently struck after the singer tweeted about being a fan of the potato snack and was subsequently approached by the company.

Perry will now be the face of the brand as its first national advertising campaign kicks off this autumn.

"I remember it was late at night, and I was craving a midnight snack without the guilt" said Perry.
