Ben Affleck and ex-girlfriend Lindsay Shookus were spotted hanging out once again, fueling rumors that they have gotten back together.

On Friday, Affleck, 45, was photographed taking a stroll with Shookus, 38, around New York City. In photos obtained by Daily Mail, the "Justice League" star bundled up in a navy blue jacket over a t-shirt of the same color, blue trousers, matching trainers and a blue beanie. He accessorized with aviator sunglasses.

Meanwhile, the "Saturday Night Live" producer looked chic in an all-black outfit, including a trench coat, turtleneck, skinny jeans and boots. Like Affleck, she also wore a beanie.

In photos from their outing, Affleck was spotted with a serious expression as he carried and sipped on a Starbucks coffee at one point during his stroll with Shookus.

Last week, Affleck and Shookus were also spotted together getting some coffee. The two seemed to be in lively moods at the time as they were photographed smiling. Shookus even flashed a grin at the camera while carying carrying two cups of what looked like iced coffee, before getting into Affleck's car.

The exes had been in a relationship for nearly a year before they parted ways in the summer of 2018. The actor entered rehab for alcohol addiction shortly after their split.

Affleck, who has sought treatment in rehab multiple times, recently underwent another stint there reportedly due to his ex-wife, Jennifer Garner. Reports claimed that back in August, Garner enlisted the help of a sober coach and a Bible when she staged an intervention after his breakup with Shookus.

Affleck and Garner tied the knot in 2005 and were married for a decade before they announced their split in 2015. They filed for divorce in April 2017 and finalized it in October last year. Nowadays, Garner and Affleck continue to co-parent their three kids, Violet, 13, Seraphina, 10, and Samuel, 6, and seem to get along well.

While Affleck seems to be reconciling with his ex, Garner's relationship with new boyfriend John Miller is still going strong. The two have been dating for months now, and reports have even claimed that wedding bells are in the couple's future.

An insider told Entertainment Tonight that Garner's relationship with Miller is very different from the one she had with Affleck.

"Jen has something very different with John than she had with Ben," the source said. "She and John are both interested in living a healthy lifestyle, working out and eating well, except for the occasional trip to Chick-fil-A! When they aren't with the kids, they take time on their own seeing movies and having romantic dinners.”
