Kourtney Kardashian 's son , Reign, addressed the long-running conspiracy theory that his real father is Justin Bieber, not Scott Disick .
After years of speculation over the true paternity of the Kardashian star's youngest child, the 10-year-old shut down the claims while appearing on Instagram Live with his sister Alabama Barker's boyfriend, Scooter Jackson.
After a viewer asked if Bieber was his father, the minor quickly shut down the rumors.
"No, he's not. Bro, I swear, Justin Bieber is not my dad. Scotty...Scotty...Scotty is my dad. I don't know how old my mom was, but I think Justin Bieber was 16 when I was born. I don't think my mom would do that," he declared.
Justin Bieber, 31, and Kardashian, 45, were romantically linked after her split from Disick, when Bieber was 22 and she was 26.
A year after Reign was born on December 14, 2014, multiple sources claimed that the Poosh founder and the Grammy winner had become engaged.
"Justin started hanging out with Kourtney only because she started going out more. He's having a great time with her," the insider told Us Weekly at the time.
The source noted that sparks started flying between them in late August, early September and progressed to nights out and a trip to Universal Studios' Halloween Horror Nights.
Bieber has been friendly with the Kardashian family for years, ever since he posed for a Mrs. Robinson-inspired Elle shoot with Kim Kardashian in 2010.
During their rumored fling, Bieber reportedly visited her house a lot to see her children and told them they loved spending time with him.
Another source said Bieber got a huge ego boost from his relationship with Kourt.
