According to People, the 45-year-old actress was on a work trip to New York City when she approached Shookus, a producer on Saturday Night Live, about the romance, however their source says that "Lindsay refused to back down or quit the affair." Since then, Garner and Shookus have not had "any relationship."

Garner has instead been keeping herself occupied by focusing on herself and her children. Here's how she's staying clear of her ex's new relationship.

Putting The Kids First

A source told ET when news broke of Affleck's romance with Shookus that his kids with Garner, 11-year-old Violet, 8-year-old Seraphina and 5-year-old Sam, will remain a priority to both of them. 

"Ben and Jen are both young, they won’t close the door on dating. It’s really nice how civil they have both been able to be during all of this," the source said. "Ben and Jen are two people who care deeply for their respective families. That dedication will continue."

Affleck and Garner have even been spotted on recent outings with their kids, celebrating the Fourth of July together and vacationing as a family in the Bahamas in June.

Hitting the Gym

Garner's endorphins must be doing the trick, as she was spotted hitting the gym four times last week. 

A source told ET that the actress is a regular at Body by Simone, and while she usually takes private sessions, she recently attended a group class and worked out in the front row. 

"[Garner is] positive, friendly, confident and really into the workout," the source revealed, adding that the mother of three isn't afraid to ask questions, and is almost always makeup-free when arriving to class.

And the hard work in the gym has clearly been playing off -- the brunette beauty looks incredible!
