Looks like Jennifer Garner shares more than just a name — and a former partner — with Jennifer Lopez.

The “13 Going on 30” star channeled her ex-husband Ben Affleck’s new wife’s casual style while reuniting with the actor at their son Samuel’s basketball game Saturday.

The 51-year-old actress attended the Santa Monica, Calif., sporting event in a mint green cardigan buttoned over a white shirt, paired with light wash jeans, brown sandals and black sunglasses.

Just last month, Lopez wore a nearly identical outfit while shopping at a flea market with Affleck.

The “Let’s Get Loud” singer, 54, kept cozy during the September outing in Sablyn’s Bianco Cardigan ($565) with a white top peeking out.

While her wide-legged jeans looked similar to Garner’s weekend attire, she chose to accessorize with colorful shades and white sneakers instead.

This isn’t the first time Garner, who was married to Affleck from 2005 to 2018, has twinned with Lopez this month.

On Oct. 6, the “Alias” alum appeared on “Good Morning America” in a floral pink Valentino skirt ($5,500) that appeared to mimic Lopez’s Bach Mai dress from the Daytime Beauty Awards one week prior.

Lopez married Affleck in 2022, becoming the stepmother to his and Garner’s three children — Violet, 17, Seraphina, 14, and Samuel, 11.

The Grammy winner has helped the former couple reach a “better” co-parenting place, the Daily Mail reported last month.

“The drama of the past and the emotions of divorce are long gone and they are all making it work,” a source told the outlet in September. “It is really a very happy co-parenting situation.”

While Garner has kept quiet about her ex-husband’s new love, Lopez gushed to Vogue about the “Last Thing He Told Me” star in November 2022.

She praised Garner for “work[ing] well” with Affleck and maintaining an “amazing” dynamic for their kids.

Perhaps the two Jens will share a closet next.
