Straight from the mom-to-be herself! Kourtney Kardashian has at last confirmed what Us Weekly first exclusively revealed on Wednesday, June 4: She and love Scott Disick are expecting their third child together! 

As seen in a preview following the Sunday, June 8, episode of Keeping Up With the Kardashians, the 35-year-old reality star will break the news to Disick during the second half of KUWTK's ninth season. The two are talking in their walk-in closet when she says simply, "I'm pregnant." 

His reaction? "What? Holy [bleep]!"

Together for seven years, Kardashian and Disick already have two kids, son Mason, 4, and daughter Penelope, 23 months. As Us previously reported, they'll welcome their child in December.

"They don't know the gender yet," a source told Us of the parents-to-be. "They just want the baby to be healthy."
