Angelina Jolie took a breather from filming her directorial debut in Budapest, Hungary on Sunday -- to plant one on beau Brad Pitt.

Pitt, 46, wasn't the only man in Jolie's life to visit her on set: on Sunday he took sons Maddox, 8, and Pax, 7, as well. See more shots of Brangelina kissing in Budapest.
