Kourtney Kardashian is taking a stand against false rumors circulating about her family — and she's not backing down when it comes to protecting her children. In a rare public statement shared on her Instagram Story on Sunday, March 2, the 45-year-old reality star addressed claims that her 15-year-old son Mason Disick had recently fathered a child.

"I rarely address rumors or conspiracies regarding myself or my family, but this is about my child and it feels wrong to let anyone think for a second that these lies are remotely true," the reality TV star wrote on her story.
