OK, so it's a rubbish ad for her new film 'Jennifer's Body' and if this is the standard of acting in it, then there'd better be a whole heap of nudity in the film to make up for it...

Pics above are of Megan (or May-gun as she pronounces it) at the Teen Choice awards - does she need a piss in this one or what?

Or you can revisit the stills from 'Jennifer's Body' where her nipples have mysteriously disappeared.
