Inside Ben Affleck & Jen Garner's Secret Holiday Rendezvous

Are Ben Affleck and Jennifer Garner making a New Year's resolution to give their marriage another try? The fractured couple is reportedly heading to Big Sky, Montana, to spend time together at the swank Yellowstone Club.

"They love it there because it's so private" a source told US Weekly of the pair's top-secret holiday plans. "It's one of their favorite places to go as a family."

While Affleck and Garner's newfound ability to spend time together without going for each other's throats is a positive sign, a source close to Affleck insists nobody should jump to conclusions about their relationship status.
