The 35-year-old already has two kids, Mason, 4, and Penelope, 23 months, both with long term partner Scott Disick.
“She is only a few months along,” says a source who saw her recently, noting that she refused to drink alcohol. Adding, “Kourtney looked really pretty. She had a nice flush on her cheeks.”
“It was planned,” a source confirmed to Us Weekly. “[Kourtney] wants to have a handful of kids.”
The baby will be born in December, confirms the source.
“They don’t know the gender yet,” the source adds. “They just want the baby to be healthy.”
Previously, a major plotline on Kourtney & Kim Take New York was Kourtney and Scott disagreeing on whether to have another baby, Scott feeling used like a “sperm donor” and the couple sleeping in separate rooms so Kourtney could attachment parent and sleep in the same bed as her minor children more often than not.
