Ben Affleck and estranged wife Jennifer Garner rang in his 43rd birthday together at Florida's Universal Studios with their three young children.

According to People magazine, the pair was spotted together in Orlando on Saturday touring The Wizarding World of Harry Potter exhibit with Violet, 9, Seraphina, 6, and Samuel, 3.

"Jennifer Garner is in the same Harry Potter shop as me WTF," tweeted one amazed onlooker.

Affleck and Garner announced they were calling it quits on their 10-year marriage back in June, but since then, the family has been seen out and about on several outings together. The two also recently accompanied their kids on a trip to the Bahamas.

Meanwhile, reps for Affleck continue to vehemently deny persistent rumors that he may have had a fling with 28-year-old nanny Christine Ouzounian. Since news of the alleged affair broke, Garner has busied herself shooting the film "Miracles from Heaven" in Atlanta.

Affleck has also been spotted making frequent trips to Atlanta to visit his children, who reportedly reside with Garner in a nearby rental home. The two were again spied together last weekend taking their children to see the film "Inside Out."

A friend of Affleck later told People, "He's happiest when he's with his family."

As for Ouzounian, the New York Daily News has reported she's rumored to be "lapping up her 15 minutes of fame" and may now be considering sitting down for a tell-all TV interview.

Reports are Ouzounian, who recently stayed at the exclusive Hotel Bel-Air (reportedly on Affleck's dime), dreams that she and Affleck may have a future together and believes "they're meant to be together."

Representatives for Affleck continue to label all the rumors as "garbage."
