Ben Affleck celebrated his 44th birthday with his estranged wife Jennifer Garner and their three children in Montana, according to People magazine. This follows several reports that claimed Garner and Affleck were working to get back together.

The “Gone Girl” star, who celebrated his birthday on Aug. 15, spent time with his family in the western state, where they own a condo.

“The family spent the week together and enjoyed outdoor activities like hiking, biking and swimming,” a source told People. “Ben is happiest when he’s spending time with his family. It was a great birthday.”

Last June, Garner and Affleck announced their decision to divorce, ending 10 years of marriage. Since then, the former couple has been spotted together on several occasions, sparking speculations that they are working to resolve their differences and get back together. The two were also reported to have held off their divorce.

However, Garner opened up about her life with Affleck and their three children on the “Today Show” earlier this month. “We are definitely a modern family,” she said. “We’re doing really well. 

“Ben was working in London on Justice League, and I felt like, well, the kids should have that experience. And he and I are great friends and we just all went en masse,” Garner said, adding: “It has to be [about being a team]. You don’t have a choice.”
