AceShowbiz - Since Kourtney Kardashian was romantically linked to Justin Bieber in 2015, rumors have swirled around the true paternity of Reign Disick, Kourtney's youngest child with ex-partner Scott Disick.

In n Instagram Live, 10-year-old Reign put these speculations to rest. When asked if Bieber, now 31, was his father, Reign firmly stated, "Justin Bieber's not my dad. Scottie is my dad." He further clarified, "I think Justin Bieber was 16 when I got born. Yea, I don't think my mom would do that."

The origins of these rumors trace back to a period following Kourtney Kardashian's split from Scott Disick during their on-and-off relationship. It was during this time that insiders claimed Kourtney and Bieber, who was then 22, had a brief romantic relationship.

A source told Us Weekly, "Justin started hanging out with Kourtney alone because she started going out more. He's been showing her a good time."

Last year, a 2014 episode of "Keeping Up with the Kardashians" resurfaced, featuring Khloe Kardashian bragging about attending P. Diddy party. Mentioning that Justin was among the guests and many of them were in various states of undress, Khloe told Kourtney, "You would have loved it!"

Kourtney and Scott Disick share two other children - Mason, 15, and Penelope, 12. They have split and Kourtney since moved on with Travis Barker, with whom she welcomed baby boy, Rocky.

Meanwhile, Justin settled down with Hailey Bieber, and they welcomed their son, Jack Blues, in August 2024.

Justin once addressed the lingering rumors with Kourtney during an interview on "The Bert Show" in 2016. He said, "I've known [the family] for years. For real, she's great."
