Ben Affleck rang in his 43rd birthday with his family.
The actor was spotted with ex Jennifer Garner and their three kids – Violet, 9, Seraphina, 6, and Samuel, 3 – at Universal Studios Orlando on Saturday.
The pair, who announced their split exclusively to PEOPLE in June, were spotted by Twitter users at Universal Orlando’s The Wizarding World of Harry Potter.
“Jennifer Garner is in the same Harry Potter shop as me wtf,” Tweeted one onlooker Saturday afternoon.
And another shared a Snapchat shot of the couple:
This is the latest public outing for the family since Affleck and Garner, also 43, brought their kids to the United States after taking a trip to the Bahamas last month.
Garner has been busy filming Miracles from Heaven in Atlanta amid rumors that Affleck had a fling with their nanny, Christine Ouzounian, 28. (Affleck sources have repeatedly denied that they ever had a romantic relationship.)
Affleck has been making frequent trip to Atlanta to visit with his children, who are staying with Garner in a rental home while she works on her project. As PEOPLE previously reported, Affleck and Garner took their children to see Inside Out last weekend.
“He’s happiest when he’s with his family,” a close friend told PEOPLE.
