The threesome were photographed during the afternoon outing while walking hand-in-hand on their way back to the Gone Girl actor's Tesla in Los Angeles, Calif.
The Deep Water star looked hunky as ever while rocking a purple button down shirt with jeans, as the "On the Floor" singer sported a casual chic look in a simple white crop top and high-waisted white pants.
The sighting comes just one day after Affleck showed support for his girlfriend as she accepted the Icon Award at the 2022 iHeartRadio Music Awards, where Samuel and Lopez's 14-year-old daughter, Emme, also tagged along. (Lopez shares twins Maximillian and Emme with ex-husband Marc Anthony, while Affleck has two other children: Violet, 16 and Seraphina, 13, with Garner.)
Affleck and Lopez — who rekindled their romance last year following their split in 2004 — have been hot and heavy ever since their reconciliation, with the duo visiting their new $50 million Bel-Air property that they purchased for their joint family over the weekend.
That same weekend, Affleck's new film, Deep Water — which he filmed with ex-girlfriend Ana de Armas — premiered on Hulu. The former couple was first romantically linked in 2020 after filming the thriller film together, although they called things off in January 2021.
After their film was pulled from theatrical release, the exes were believed to be relieved that they wouldn't be attending any awkward premieres together since they have both moved on from their former romance, as OK! reported. de Armas has since sparked a romance with Tinder executive Paul Boukadakis.
Meanwhile, Lopez's ex-fiancé, Alex Rodgriguez, seems to be loving the single life ever since the former flames broke off their engagement in April 2021.
Despite reports that the former athlete was still hung up on Lopez, an insider dished earlier this year that A-Rod is "single" and just "enjoying life," while spending time with rumored flame Kathryne 'Kat' Padgett.
