Jennifer Garner visits and celebrates her Ex. Ben Affleck on his birthday while Jennifer Lopez gushes over her own big day that is more important

Jennifer Garner was spotted visiting ex-husband Ben Affleck on his birthday on Thursday as his marital woes with current wife Jennifer Lopez continue.

The “13 Going on 30” star wore a striped white T-shirt and a pair of navy trousers during her stop at his Brentwood, Calif., rental home.

She accessorized her look with a pair of glasses and simple jewelry which included some dainty silver earrings and an Apple watch.

Things appear to still be friendly between the exes — who divorced in 2018 and continue to maintain their “mature” co-parenting relationship while raising their three children: Violet, 18, Seraphina, 15 and Samuel, 12.

The actress even made a light-hearted joke about her split from Affleck in the new “Deadpool & Wolverine” film as she made her return to the Marvel Cinematic Universe as Elektra.

Garner’s visit comes shortly after Lopez posted throwback solo photos from her own birthday on Instagram — the same day her estranged husband celebrated his 52nd birthday — further fueling rumors of the couple’s pending split.

The “On the Floor” singer spent her most recent birthday in the Hamptons as she and Affleck continue to live separate lives. She held her birthday dinner at Nick & Toni’s restaurant where she wore a sparkly sheer Dior Haute Couture gown before she hosted a “Bridgerton”-themed party.

Affleck and Lopez also spent their second wedding anniversary on different coasts in July.

The couple has been rumored to be heading for divorce since May after fans noticed Affleck was absent from Lopez’s side at the Met Gala.

Page Six previously learned that Affleck was ready for a divorce after he “came to his senses” on the relationship with sources saying he felt he was in a “fever dream” with his whirlwind relationship.

He also skipped all of Lopez’s “Atlas” press tour and film premieres.

Garner was reportedly supportive of her ex and even pushed him to “work on his marriage” with Lopez.

Lopez and Affleck, who tied the knot in July 2022, officially put their marital mansion up for sale in July. The “Argo” star has already found some new digs in the Pacific Palisades while Lopez continues to search for her own home in Los Angeles.
