VIDEO : Charlize Theron and Sean Penn Keep Distance at Cannes

Luca Teuchmann/Getty Images And this is why dating a co-worker can get awkward. Charlize Theron and Sean Penn are at the 2016 Cannes Film Festival premiering their new movie, The Last Face , which would totally be a normal thing to do in the film industry, but given that these two stars had a bad breakup, it has to be especially painful. Penn directed his latest film, which just so happens to be getting panned across the board. It's bad enough that these two have to pose for pictures together?although they're doing their best do keep their distance?but to have the movie get trashed probably adds insult to injury.
