Jennifer Garner had allegedly confronted Lindsay Shookus over her alleged affair with Ben Affleck back in 2013. The 45-year-old actress reportedly asked the Saturday Night Live producer to end the relationship with the Oscar-winning actor back then.

A source told Us Weekly: "Lindsay said she'd only stop if Ben asked her to. It was the breaking point for Jen."

However, sources close to Affleck and Shookus are denying the reports, and maintain that the two were just friends, and did not date before splitting up with their respective partners.

Affleck and Garner officially filed for divorce in April, after a two-year separation. The couple, who announced they are calling it quits on their marriage just one day after their 10th wedding anniversary in 2015, seeked joint custody of their children, Violet, 11, Seraphina, 8, and Samuel, 5.

Shookus got married to Kevin Miller, a former SNL producer, in 2010. The two have a daughter together.

The Argo star and Shookus were spotted on a date night on July 6 in Los Angeles. Adding on, the new couple were also pictured while heading out of Beech Street Cafe on July 10 in Pacific Palisades, California.

Previously, Affleck's affair with his children's former nanny, Christine Ouzounian was cited as reason for divorce with Garner. However, the Daredevil had defended her former husband saying: "Let me just tell you something. We had been separated for months before I ever heard about the nanny."

Garner explained: "She had nothing to with our decision to divorce. She was not a part of the equation. Bad judgment? Yes. It's not great for your kids for [a nanny] to disappear from their lives. I have had to have conversations [with my children] about the meaning of 'scandal.'"
