Scott and Lindsay began the night at a bar in the East Village around 10 p.m. and ended with the two of them going back to Scott's hotel after 6 a.m.
"Kourtney surprisingly isn't fazed by this at all," a source close to Kourtney tells ET. "She's moving on. She knows it's just a fling."
For now, Kourtney is keeping the focus on her health and three children, Mason, 5, Penelope, 4, and Reign, 9 months.
"She's trying hard to ignore it and just focus on the kids," the source adds. "She knows they'll never get back together."
