'If You Can Afford Me' chanteuse Katy Perry has signed up to be the face of 'healthy' crisp altern­at­ive Popchips.

"I was hooked after my first bite!" Perry exclaimed to a press release (as quoted here). "When I discover something good, I want to share it with everyone I know, so I tweeted about it."

These tweets were of course com­pletely arbitrary and were in no way part of a longer campaign of viral marketing. (We called this one back in May.)

As well as appearing in some adverts, Perry will also be investing in the company and joining the likes of P Diddy as a creative partner.

What a load of old shit.
