Three months after filing for divorce from his wife of 10 years, Jennifer Garner, the 44-year-old actor has moved on with a blond beauty who works behind the camera. ET can confirm that Affleck is dating Lindsay Shookus, a producer at Saturday Night Live.
"Ben and Lindsay have known each other for a couple of years," a source told ET on Friday. "Ben has been on SNL five times and has met Lindsay while hosting the show. It is early on in the relationship but they are very happy together."
According to the source, the two began dating sometime after Affleck and Garner split in June 2015. Affleck and Garner officially filed for divorce in April, nearly two years after announcing they were separating.
The source says Affleck's new relationship works "really well," because Shookus "has had experience with the Hollywood world."
"[She] knows what is expected of Ben, and how much of their relationship they can share publicly," the source explained. "It puts Ben at ease knowing that Lindsay understands who he is. They have kept their relationship very low key and private."
Despite the excitement of his new relationship, Affleck is still fully focused on the three children he shares with Garner, daughters Violet, 11, and Seraphina, 8, and son Sam, 5.
"Ben is still all about his children first," the source said. "He always will be -- that to him is paramount in his life. He's doing the family thing. Even when [he and Jennifer] separated two years ago, there were so many people who wanted them to get back together but they knew that they would move on."
"Ben and Jen are both young, they won't close the door on dating," the source added. "It's really nice how civil they have both been able to be during all of this. Ben and Jen are two people who care deeply for their respective families. That dedication will continue."
No word on whether Shookus has met Affleck's kids just yet, but the source told ET that if it does happen, "you can be sure the situation will be dealt very delicately."
As for Shookus, she was married to fellow SNL producer, Kevin Miller, according to The New York Times.
