Kourtney Kardashian Blasts Rumor That 15-Year-Old Son Mason Has Kid

Kourtney Kardashian is firing back at speculation she’s a grandma … blasting trolls online for spreading a rumor that her 15-year-old son is a teen father!

The reality television star jumped on Instagram Sunday to address internet speculation that her son, Mason Disick, has a kid of his own … saying she doesn’t usually address insane gossip like this, but felt she needed to step in for her child’s sake.

KK straight up denies the rumor … calling it a conspiracy and claiming many social media accounts pretending to be Mason are fake — and, they’re spreading lies about him.

Kourtney adds that Mason likes his privacy … and, she’s asking everyone to be respectful of it — before calling on trolls to stop making videos about her minor kids.

ICYMI … rumors about Mason allegedly having a 1-year-old child sparked when someone posted — then deleted — screengrabs on Reddit from a private Instagram account they said belonged to Mason.

While some ran with the false narrative, many questioned it from the beginning … claiming it’d be hard for a Kardashian to keep a kid secret for more than year given the amount of attention the family attracts
