He didn't waste any time!

Practically every major media outlet is reporting that Ben Affleck and Lindsay Shookus split in late July, weeks before his first date with Playboy model Shauna Sexton at Nobu Malibu on August 16, but that's just not true!

We caught the SNL producer hugging Ben's sober mentor and Refuge Recovery founder Noah Levine at the actor's Pacific Palisades mansion on August 9, and apparently she called him over because things with the actor were going downhill and he was in a bad place.

A source with direct knowledge of the situation tells X17:
    "Ben's sober coach made the house call because Ben was in a bad way. Lindsay got fed up with dealing with Ben's issues, and ultimately that's what led to the end of the relationship."

A lot of people would assume that Jen Garner is less than pleased that the father of her children is hooking up with a pinup girl, but she's actually just glad that Lindsay is out of the picture.

The same source tells us:
    "Jen is thrilled that Ben and Lindsay are over. She would rather he be with anyone but Lindsay, since she was the mistress that broke up their marriage. Of course, she thinks it's childish and ridiculous that he's going after a Playboy model half his age, but she'll take it. Jen's worst fear was Ben popping the question to Lindsay and having another baby, so she's relieved she doesn't have to worry about that anymore."

Karma is real, people!
