Ben Affleck and ex-girlfriend, 'SNL' producer Lindsay Shookus, are back on: report

They're on. They're off. Okay, they're on again.

Ben Affleck was spotted multiple times with ex-girlfriend Lindsay Shookus in L.A. this weekend, including a morning Starbucks run and a dinner date: "They've picked right back up where they left off," Us Weekly reports.

On Saturday, Affleck attended a wedding with ex-wife Jennifer Garner and two of their children. He wore a dark blue suit and showed up for dinner with Shookus hours later in the same outfit.

ET reports that the two, who broke up mid-summer 2018, have been "hanging out" for "over a month." Their split was confirmed when Affleck openly began a relationship with Shauna Sexton, a then-22-year-old Playboy model.

It was a few weeks after his split from Shookus that, upon an intervention from Garner, Affleck entered a rehab problem for alcohol abuse.

“Jen was incredibly concerned because Ben was making excuses for missed plans and rarely answering his phone in the week before he entered rehab," ET reported at the time. "She knows this pattern very well and became worried.”

While Affleck has dealt with some career changes since completing rehab -- he was slated to direct and star in the next "Batman" but revealed earlier this year he'll no longer do so -- Shookus has seemingly settled back into her normal routine as a producer at "Saturday Night Live." She's recently posted Instagrams from the show's home at 30 Rockefeller Plaza.
