Ben Affleck 'had a really good time' on birthday with ex Jennifer Garner

Ben Affleck had a "great" birthday weekend with Jennifer Garner.

The Oscar winner, who recently split from the 'Butter' actress after 10 years of marriage, was photographed looking rather unhappy while celebrating turning 43 on Saturday with his estranged wife and their three children, Violet, nine, Seraphina, six, and Samuel three, at the Wizarding World of Harry Potter in the Universal Orlando Resort.
