Jennifer Garner was seen visiting her ex-husband Ben Affleck on his birthday Thursday, amidst ongoing marital issues between Affleck and his current wife, Jennifer Lopez.

Despite their 2018 divorce, the exes seem to maintain a friendly relationship, co-parenting their three children: Violet, 18, Seraphina, 15, and Samuel, 12, with a "mature" approach.

Garner even made a playful reference to her split from Affleck in the upcoming "Deadpool & Wolverine" film, where she returns to the Marvel Cinematic Universe as Elektra.

Garner's visit follows Lopez's recent Instagram post of solo throwback photos from her own birthday, shared on the same day as her estranged husband's 52nd birthday, which has further fueled rumors of their potential separation.

The "On the Floor" singer spent her recent birthday in the Hamptons, as she and Affleck continue to lead separate lives. She celebrated with a dinner at Nick & Toni’s restaurant, donning a sparkly sheer Dior Haute Couture gown, before hosting a "Bridgerton"-themed party.

Affleck and Lopez also marked their second wedding anniversary apart, on different coasts, in July.

Rumors of a possible divorce have swirled since May when fans noticed Affleck was absent from Lopez’s side at the Met Gala.
