Jennifer Garner was spotted in good spirits while hitting the gym in Los Angeles Saturday, just days after she returned from a vacation in Montana with her estranged husband Ben Affleck, Daily Mail reported. Garner and Affleck sparked reconciliation rumors after the two went for a family getaway during the Valentine’s Day weekend.

The 43-year-old actress was reportedly seen in a skintight exercise gear as she showed off a big smile after her workout when paparazzi captured her. Garner was wearing a long-sleeved, black T-shirt paired with leggings, and blue- and pink-colored sneakers.

According to Page Six, Garner and Affleck were recently spotted spending a family vacation together in Montana, along with their three children Violet, 10, Seraphina, 7, and Samuel, 3. The estranged couple was also reportedly joined by Tom Brady and his wife Gisele Bundchen at the Yellowstone Club in Big Sky Country.

“There were no nannies in sight, but Jen doesn’t look like she is harboring any resentment. Jen and Ben weren’t lovey-dovey at all, but were super-friendly and happy, relaxed,” a source told Page Six. “They were both attentive to their kids and laughing with Tom and Gisele.”

Despite rumors that Garner and Affleck may be planning to hold their divorce, Us Weekly reported that their main motive to spend time together is for the sake of their children.

“They want their kids’ childhood memories to still be good,” another source told the magazine. “They’re together only for the kids, not romantically.”

People magazine had also reported that Affleck’s relationship with his estranged wife is more of friendship.
