The 49-year-old actress was photographed being a completely normal parent, taking their three children to Staples for supplies in West Los Angeles over the weekend.
Keeping it casual for her outing with her 12-year-old daughter, Seraphina, and her 9-year-old son, Samuel — both who she shares with Affleck — Garner was photographed wearing light-colored jeans, a black shirt, and sneakers.
Her ex-husband and their oldest child, 15-year-old daughter, Violet, were nowhere in sight.
Wearing her brown hair back in a sleek ponytail, the 13 Going On 30 actress slipped on a pair of oversized sunglasses and a hot pink mask, making it virtually impossible for the paparazzi to miss her.
Emerging with bags of goodies from the supply chain, Garner was clearly laser-focused on getting her children ready for the school year ahead while her ex-husband had something else completely on the brain.
Garner's mom of the year outing will certainly score her brownie points with her former mother-in-law, who was seen chumming it up with J Lo over the weekend.
Affleck's mother was also spotted accompanying her 49-year-old son to look at engagement rings on Monday.
The Academy Award winner and J Lo have only been together four months, but it seems he's ready to take the next step.
As Radar reported, Affleck was caught browsing for engagement rings at Tiffany & Co. just hours ago.
Attempting to go incognito, he wore a mask and shades but he didn't fool photographers who were standing outside the pricey shop waiting for the perfect shot.
While Affleck didn't appear to leave Tiffany's with a diamond in tow, the fact that he's looking is huge.
As fans will recall, this wouldn't be the first engagement ring he's bought J Lo.
Affleck first popped the question in November 2002. They were set to wed in 2003 but canceled their wedding last minute, sighting too much media coverage.
Months later, Affleck and J Lo ended their relationship, only to each get married to someone else, have children, and find their way back to each other nearly 20 years later.
