Actor-director Ben Affleck spent his 43rd birthday Saturday with his estranged wife Jennifer Garner and their three children at Universal Studios Orlando.

People magazine said the family was spotted in the Florida theme park's The Wizarding World of Harry Potter section, marking the first public outing for the divorcing couple since Affleck and Garner brought their kids -- Violet, 9, Seraphina, 6, and Samuel, 3 -- home to the United States after a trip to the Bahamas last month.

Affleck and Garner announced in June they are ending their 10-year-long marriage.

Affleck has since been dogged by rumors he had an affair with his children's nanny, a story sources close to Affleck have vehemently denied.
