Kourtney Kardashian’s Son Reign Addresses Rumor Justin Bieber Is His Biological Father

Kourtney Kardashian and Scott Disick’s youngest son, Reign Disick, is shutting down the rumors that his biological father is actually Justin Bieber.

While appearing on a recent Instagram Live alongside his stepsister’s (Alabama Barker) boyfriend, Scooter Jackson, the 10-year-old addressed the speculation after a social media user asked about the scandalous conspiracy theory.

“He’s not, bro, I swear,” Reign said of the “Peaches” singer. “Justin Bieber’s not my dad. Scotty, Scotty, Scotty is my dad.”

Reign added, “I don’t know how old my mom was, but I think Justin Bieber was 16 when I got born. I don’t think my mom would do that.”

Kardashian, 45, and Disick, 41, are also parents to 15-year-old son Mason and 12-year-old daughter Penelope. The pair dated on and off until they officially split in 2015.

Kardashian was romantically linked to Bieber, who was about 21 at the time, shortly after she and Disick called it quits. The reality star went on to welcome son Rocky Barker with now-husband Travis Barker in 2023.

“They have hooked up a few times, including recently. It happens in LA,” a source told People of Kardashian and Bieber in April 2016. “He has met her kids, but they don’t hook up around the kids. It’s on nights when she has help and is able to go out.”

HuffPost has reached out to Kardashian’s reps for comment.

Kardashian and Disick’s other son Mason also found himself embroiled in rumors a few weeks ago after the internet accused him of secretly fathering 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,” she wrote in an Instagram story last month. “They are not. Mason does not have a child. These accounts that pretend to be him are definitely not. They are FAKE.”

The Poosh founder asked social media users to “please be respectful” because “he is a kid with feelings and a beautiful life ahead of him.”

Kardashian added: “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.”
