Jennifer Garner confronted Ben Affleck‘s girlfriend Lindsay Shookus in person after she found out about their affair in 2015, sources tell PEOPLE.
Garner was on a work trip to New York City when she approached Shookus about the fling. “Lindsay refused to back down or quit the affair,” says a source.
Responds a source close to Shookus: “Jennifer and Lindsay do not have any relationship.”
Multiple sources have told PEOPLE that Affleck and Shookus started having an affair in 2013, two years before the actor and Garner announced their separation. Shookus was also still with her husband Kevin Miller, then a fellow SNL producer. The two split in 2014.
However, other sources close to Affleck and Shookus maintain that the two were just friends and didn’t date before their respective separations.
Sources also say Garner spoke to Shookus’ ex about the affair. After appearing on an episode of Late Night with Seth Meyers, where Miller is now a supervising producer, Garner sought him out for a conversation.
The first source says she showed him text messages between Affleck and Shookus, adding, “she had proof.” (Miller and Shookus were already split at the time.)
Affleck and Shookus have been spending time together in L.A. since going public with their relationship last week.
