The 49-year-old actress is a plain Jane when it comes to fashion, but the idea that her ex might be replacing her officially with the Bronx-born bombshell may have sent her spinning.
Turning the Los Angeles streets into her own personal runway, Garner strutted around in her bridal-worthy dress on Tuesday, just hours after Affleck was spotted looking at engagement rings.
Keep in mind while the couple dubbed "Bennifer" has only been together for four months, this isn't their first rodeo — and wouldn't be their only engagement.
Affleck popped the question to J Lo in November 2002. They even had a wedding set for 2003 but canceled it days before walking down the aisle. In January 2004, the duo announced they had separated.
Of course, they went on to marry other people and have children.
Affleck famously married Garner in 2005. They welcomed three kids together — Violet, 15, Seraphina, 12, and Samuel, 9 — but their marriage didn't last.
Affleck and Garner officially divorced in 2018 after being separated for some time.
Fast-forward to three years later, Garner doesn't want the Justice League star to forget the OG, who followed through with their wedding plans — unlike J Lo.
Making her own headlines in a head-turning floor-length dress, Garner stepped out in all white and looked like a sun-kissed goddess.
Slipping into the flowing pure attire, she knew exactly what she was doing when she hiked up the dress and hit the perfect angles for the nearby paparazzi.
Wearing white accessories and toning the look down with sneakers, Garner showed her ex that two can play the game.
As Radar reported, Affleck was caught browsing the engagement ring aisle at Tiffany & Co with his mom and son on Monday.
While he attempted to go incognito, Affleck was no match for shutterbugs who eagerly captured photos of the Academy Award winner looking at diamonds.
Affleck didn't appear to walk out of the ritzy store with a purchase, but J Lo was spotted sporting a gigantic diamond ring just hours later.
