What Ben Affleck was up to while Jennifer Lopez was celebrating her birthday in the Hamptons

Ben Affleck was spotted without his wedding ring over the weekend as Jennifer Lopez partied it up in the Hamptons for her 55th birthday.

The “Argo” actor ditched the sentimental piece of jewelry while out and about in Los Angeles on Sunday.

Affleck, who sported a red T-shirt and gray pants, was photographed running some errands as his wife was across the country hosting a birthday lunch.

The following day, Affleck was all business as he arrived at his office wearing a navy suit.

The Oscar winner, 51, carried an iced coffee in his right hand and his phone and gym bag in the other, making it hard to tell if he was wearing his wedding band.

Meanwhile, Lopez was seen wearing her bedazzled band while at an Equinox location in the Hamptons on Monday.

The “Jenny From the Block” singer flashed her abs in a cream sports bra, low-slung white linen pants and a fuzzy, oversized cardigan.

Lopez was dressed for comfort after coming off a jam-packed celebratory weekend. The “Wedding Planner” star kicked off the birthday festivities with a lavish “Bridgerton”-themed party on Saturday at her Hamptons’ rental.

Guests, including several of Lopez’s family members, arrived at the soirée dressed to impress in Regency-inspired fashion. They were greeted at the entrance by a horse-drawn carriage before heading inside for the lavish fête.

The following day, Lopez hosted an intimate lunch with her closest family and friends at Arthur & Sons.

All eyes were on J.Lo as she arrived in a white romper with floral accents and a large gold statement necklace. She wore her hair up in a sleek bun and added a pair of blue-tinted sunglasses.

We’re told the “Hustlers” actress — who was joined by her twins, Max and Emme, and sister Lynda — got emotional at the table while telling stories about her past.

In addition to her birthday, Lopez and Affleck were also apart for their 2-year wedding anniversary on July 16.

While the singer was seen riding around in the Hamptons with manager Benny Medina, Affleck was business as usual in LA.

Although neither of them has publicly addressed the state of their marriage, an insider recently told Page Six that it has “been over for months.”

Rumors of trouble in paradise started to swirl in May after the actress attended the Met Gala solo despite being one of the event’s co-chairs.

Soon after, the “Good Will Hunting” star moved out of the pair’s massive Beverly Hills mansion, which they recently listed for $68 million.

The couple are reportedly in a “rush to sell” the 38,000-square-foot property, which they bought in all cash just one year ago.
