Kourtney Kardashian is NOT carrying her fourth child with Scott Disick, despite some strong speculation she’s pregnant.

As you know … the trailer for “Keeping Up With the Kardashians” season 19 dropped last month, insinuating Kourtney and Scott are back together and she’s having his baby.

Kourtney’s recent Instagram post, featuring a shadow some eagle-eyed fans thought looked like a baby bump, kept the rumor mill churning … but we’ve learned that’s simply NOT the case.

Sources close to Kourtney tell 360APROKO … she is not pregnant again and she’s happy being a mother of 3. As for the ‘KUWTK’

Bottom line … our sources say Kourtney and Scott are not together as a couple, they’re just very good friends and co-parents.
