Exes Charlize Theron and Sean Penn Awkwardly Reunite at Cannes — See the Pics! - Closer Weekly

Well, this is awkward!

Exes Charlize Theron and Sean Penn had an uncomfortable reunion at the Cannes film festival on Friday, May 20. This is the first time the former couple — who were promoting their new movie, The Last Face — appeared together in public since calling off their engagement in June 2015.

During a Cannes photocall, Charlize, 40, and Sean, 55, kept their distance by ensuring several of their costars separated them during cast pictures. The duo additionally refrained from interacting at a The Last Face press Q&A later in the day.

But, the pair did surprisingly acknowledge each other with a painful-looking kiss Friday evening when they again came together on the movie’s premiere red carpet. So cringe-worthy!

The Monster star and Sean — who were previously rumored to be engaged — began dating in early 2014 and ended their relationship just more than a year later. “We were in a relationship and then it didn’t work anymore. And we both decided to separate. That’s it,” Charlize said following their split.
