VIDEO : Exes Charlize Theron & Sean Penn Reunite for South African Re-Shoots--See the Pics

Well this could've been awkward.
Exes Charlize Theron and Sean Penn were spotted looking fairly tense while filming re-shoots on the South African set of their flick, The Last Face.
The duo has been hard at work on the future flick since last year, where they were seen together in Cape Town shooting an action scene. Penn is directed the movie, while Theron stars alongside Javier Bardem and Blue Is the Warmest Color's Adele Exarchopoulos.
The photos mark the first time that the two have been spotted together since the news of their split went public mid-June
