Jennifer Garner, Ben Affleck vacation with Gisele Bundchen, Tom Brady

BIG SKY, Mont., Feb. 17 (UPI) -- Jennifer Garner and Ben Affleck are reportedly vacationing with Gisele Bundchen and Tom Brady in Big Sky, Montana.

The 43-year-old actress and Affleck were spotted with the 35-year-old model and Brady at the exclusive Yellowstone Club ski resort Monday, according to Page Six. The getaway comes nearly eight months after Garner and Affleck announced their split.

"They had some serious après-ski and shut the bar down," a source told the publication. "Jen and Ben weren't lovey-dovey at all, but were super friendly and happy, relaxed. They were both attentive to their kids and laughing with Tom and Gisele."

"They are not back together -- they have just found a new normal where they get along and work together for the sake of the kids," a different insider clarified. Garner and Affleck share 10-year-old daughter Violet, 7-year-old daughter Sera and 3-year-old son Sam.

E! News reported prior to Valentine's Day the estranged couple was planning to spend the weekend as a family. A source told People the two often see each other but qualified, "You can tell that they are not together."

"[Jennifer] seems much more relaxed and is enjoying life," an insider said, with another adding, "They're not [best] friends, but they share in the joy of their children ... They are doing it their own way. And that way works for them right now."

Garner and Affleck confirmed their intent to divorce in June after 10 years of marriage. They have yet to officially file for divorce, although a source told TMZ at the time the pair will file after they resolve all property and custody issues.
