"Ben and Lindsay have known each other for a couple of years," a source told ET. "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."
"[She] knows what is expected of Ben, and how much of their relationship they can share publicly," the source continued of Shookus and Affleck's romance. "It puts Ben at ease knowing that Lindsay understands who he is. They have kept their relationship very low key and private."
Shookus may be private about her relationship with Affleck, but her professional accomplishments are well known. Here are seven thing to know about the 37-year-old producer.
1. She's From New York
Shookus hails from Buffalo, New York, where her dad is in the housewares and consumer products business, and her mom is a sales representative, according to The New York Times. The blonde beauty left the East Coast for college, when she attended the University of North Carolina at Chapel Hill.
2. She's a Power Player
The producer was featured on The Hollywood Reporter's Next Gen 2015: Hollywood's Up-and-Coming Execs 35 and Under list for her work on Saturday Night Live, where she's worked up the ranks after starting as an assistant to a producer right after college.
Shookus seems to go way back with Affleck's pal, Matt Damon, as the actor hosted Saturday Night Live during Shookus' first week on the show. "I remember thinking, 'How is this my job?'" she told THR.
4. She's Got an Eye for Talent
"When I started as an assistant at SNL, I got my eyes on Kristen Wiig and was able to bring her for an audition for Lorne Michaels and the other producers," Shookus, who also hired Vanessa Bayer and Jon Rudnitsky, told THR. "Turns out, Kristen Wiig can give you some street cred early on."
Shookus opened up about motherhood during her 2015 profile with The Hollywood Reporter.
"My 2-year-old has become my alarm, so on a good day, 7:30 a.m. or 8 a.m. My alarm sounds something like, 'MAMA, where ARE yooooou?'" she joked.
6. She Enjoys Fine Dining
Shookus and Affleck were spotted enjoying a delicious dinner at Giorgio Baldi in Los Angeles last week, according toE! News, where they shared lobster and pasta dishes, with a side of PDA. They were "very intimate and touchy," the outlet reported.
