Entertainment Movies Ben Affleck and Jennifer Garner Looked 'So Tense and Uncomfortable' During Trip to Disney World: Onlooker The tension between Ben Affleck and Jennifer Garner continued during a family trip to Disney World on Sunday By Mike Miller Published on August 17, 2015 09:00 PM Share Tweet Pin Email Photo: Fernando Lucena/Startraks Not even the happiest place on Earth could ease the tension between Ben Affleck and Jennifer Garner. The recently split couple visited Disney World together with their children on Sunday, as part of Affleck’s 43rd birthday celebration, but an onlooker tells PEOPLE they had “no interaction at all” with each other. They looked “so tense and uncomfortable,” another onlooker notes. “When she was around him, you could see the tenseness. Her shoulders would rise up.” While Affleck and Garner spent time individually with the kids – Violet, 9, Seraphina, 6, and Samuel, 3 – “There was never a point that all of them were really [interacting] together,” according to the onlooker. The family and a few friends arrived at Fantasyland in the morning, and got to skip the long lines for rides like It’s a Small World, Peter Pan’s Flight, Mickey’s PhilharMagic, and even took a special tour of Cinderella’s Castle. When Affleck and Garner accompanied the kids on the Dumbo the Flying Elephant ride (which they went on twice in a row) the couple rode on elephants near each other, an onlooker says. The awkwardness of their reunion echoes reports from Saturday, when the family visited the Wizarding World of Harry Potter at Universal Orlando together, where another onlooker says, “Neither of them looked too happy.” But a source close to the couple told PEOPLE they were focused on putting their children first. “As always, it’s about the kids and they will always put them first,” the source said. “Everyone had fun. They put them first no matter what.” “All Ben wanted for his birthday was to be with his children.” Since announcing their split in June, Affleck and Garner have remained committed to spending time together with their kids. In addition to announcing their divorce while on a family trip to the Bahamas, the pair has spent time together with their children in Atlanta, where Garner is filming Miracles from Heaven. The latest family trip comes amid reports of an alleged affair between Affleck and the family’s former nanny, Christine Ouzounian, 28. Affleck has denied there was any infidelity.
