Something tells us this image of Jen, complete with mega-dodge stuck-on-head Photoshop job, is not an authorised endorsement from the actress herself. But by god is it funny.

Is there a world of fake celeb knicker packets out there that we're unaware of? If you have any snaps of stars with dodgy stuck-on heads gracing the aisles of foreign supermarkets - do us all a favour and post us the URL below!
