Ben Affleck and Jennifer Garner seem to be one of the most separated-yet-amicable couples of Hollywood. The pair was recently spotted on a cozy ski vacation along with another celeb couple, Tom Brady and Gisele Bundchen, in Montana.

The estranged couple and their kids were reported to be staying in the exclusive Yellowstone Club in Big Sky, along with the Patriots star and his supermodel wife. The group indulged in some serious après-ski on Feb. 15, Monday, followed by a whole night drinking session.

"They started drinking bloody marys, then beer and bourbons. They kept the bar open late for them," Page Six quoted an eyewitness as saying. The group was later joined by CBS journalist Sharyn Alfonsi and husband Matt Eby.

Despite the ongoing divorce proceedings and much-talked about the alleged nanny affair, both Garner and Affleck looked extremely friendly and happy. Both of them were reportedly attentive to their kids but did not behave "lovey-dovey" at all.

The vacation comes almost six months after Affleck's nanny Christine Ouzounian shared a controversial pic of herself seated in the actor's private jet while sporting Patriots quarterback's championship rings on her fingers, which led to the speculation that the pair went to Las Vegas together for a charity poker tournament.

Affleck's alleged fling with Ouzounian had reportedly contributed to the breakdown of his marriage with Garner.

Despite the rift in their relationship, both Garner and Affleck seem to be steadfast in remaining a united front for the sake of their kids, Violet 10, Seraphina 7, and Samuel, 3. They always try to take time out of their busy schedules to spend some time together as a family so as not to tarnish the kids' childhood memories.

The former couple even chose to spend Valentine's weekend together as a family before heading for a ski break in Montana, People reported.

Meanwhile, Affleck has almost finished filming his upcoming film "Live By Night." Another of his most talked-about movie, "Batman V Superman: Dawn Of Justice," is also set for release on March 25.

The 43-year-old actor, who is suiting up as Batman for the first time, declared in "Good Morning America" recently that he sought advice from George Clooney to portray the character well. Catch the glimpse of the show below:
