The 43-year-old Oscar winning actor, who recently split from the "Elektra" actress after 10 years of marriage, was photographed celebrating his birthday with his three children, Violet, nine, Seraphina, six, and Samuel three, reported Us Weekly Magazine.
"This was all he wanted to do for his birthday, go to Disney World with his family and that included Jen. They planned this and all went to Orlando together. They had a great day," a source said.
Another insider, however, said Garner put on a happy face for their children.
"It was clear they were together for the kids and putting up a united front. They didn't outwardly appear to be having a ton of fun. But they weren't rushing around, and kept telling the kids they would do whatever they wanted.
