Kourtney Kardashian has slammed gossip suggesting her son Mason has become a father at the age of 15

In a statement posted on Instagram, 'The Kardashians' regular wrote: "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. They are not. Mason does not have a child."

She went on to explain Mason has fallen victim to online hoaxers who set the story in motion using fake social media accounts.

Kourtney added: "These accounts that pretend to be him are definitely not. They are FAKE. My son really values his privacy, and I am asking all media to please be respectful: he is a kid with feelings and a beautiful life ahead of him.

"Please stop spreading false narratives and spinning lies. And to all the other people making videos about my kids (who, by the way, are minors), please stop and leave them alone."

Kourtney is also mother to Penelope, 12, and Reign, 10, with Scott - who she split from in 2015 - as well as her youngest son Rocky, 16 months, with her husband Travis Barker.

The false story about Mason originated online from an Instagram account purporting to be the teenager's secret page on the platform with the hoaxers posting pictures of a baby and later claiming the youngster was dad to a baby daughter named Piper.

Mason lives with his dad Scott and the reality regular recently opened up about the dating advice he's given the teenager.

During an appearance on Khloe Kardashian's 'Khloe in Wonder Land' podcast, Scott explained: "Recently, he's starting to really like girls. And obviously, girls like him.

"[I tell Mason] 'You can do whatever you want, but just don't lie and don't manipulate any girls'.

"So if a girl tells you she maybe wants to do something with you, like hookup and whatever, if she knows you're not in a relationship with her, don't tell her you are just to get something out of her.'

"And he's like, 'No, I know, I get it'. And I hear him on the phone, he's like, 'We can but we're friends'. And he tells them straight up. Because that's where it's f***** up."
