The 49-year-old actress was spotted at a local Farmer's Market in Los Angeles, shopping to feed her family while her ex-husband lived his best PDA-filled life for the Love Don't Cost a Thing singer's birthday.
Garner appeared downcast and cold while putting on a brave face in public, just hours after Affleck broke the Internet by grabbing hold of J Lo's perfect backside on their $130 million luxury mega-yacht.
After the grab heard around the world, Affleck's ex-wife hit the local market to shop for fresh produce.
Dressing in all black like she was going to a funeral, Garner went makeup-free and rocked her black-rimed glasses.
Wearing her hair in a long braid, the 13 Going On 30 actress pulled down her mask to pick out fruits and veggies like grapes, lettuce, broccoli, and more healthy goods for the three children she shares with Affleck -- Violet, 15, Seraphina, 12, and Samuel, 9.
While Garner unhappily shopped, her ex-husband couldn't keep his hands or lips to himself.
As Radar reported, days after the couple made their Instagram debut, the Academy Award winner escaped real-life for a weekend getaway with J Lo on her 52nd birthday.
Affleck and the Hustlers actress got the hell out of Dodge but somehow ended up in the same place as her most recent ex-fiancé, Alex Rodriguez.
Despite being in Saint-Tropez on their yacht just hours after A-Rod was seen on his, J Lo packed on the PDA with the actor and clearly didn't care who saw -- even if it was her former almost-husband.
Wearing a stunning multicolored mini dress, J Lo flaunted her killer curves while Affleck bent her over the railing and put his hands all over her.
If the two stared out into the sea hard enough, they could have probably spotted A-Rod.
On Friday, the ex-Yankee was photographed having the time of his life on his yacht with several bikini-clad babes.
J Lo and Affleck are done sneaking around.
They are flaunting her relationship every chance they get, and despite sources claiming Garner didn't want to be a part of the Bennifer "circus," she can't get away.
