The reality TV star — who is currently expecting her third child with long-term beau Scott Disick — broke the news during an episode of Kourtney and Khloe Take the Hamptons which aired Sunday in the U.S.

“I’m so happy we’re having a boy,” the 35-year-old Kardashian said after finding out the sex. “It’s going to be perfect for our family.”

The famous parents already have two adorable children together, five-year-old Mason Dash, and two-year-old Penelope Scotland.

Kourtney is due to give birth later this month and has been enjoying her final few weeks of pregnancy. She recently posed nude for DuJour magazine and spoke about embracing her changing figure.

“It’s such an amazing feeling, the transformation that your body goes through,” she said. “There’s something about that that’s so empowering and beautiful and I just really embrace it.”
