Kourtney Kardashian’s son has finally spoken out about the wild rumors that Justin Bieber is his father.
The 10-year-old dismissed the claims during an Instagram Live session with his stepsister Alabama Barker’s boyfriend, Scooter Jackson.
When a viewer asked if Bieber, 31, was his father, the 10-year-old quickly shut down the speculation, confirming that Scott Disick is his biological dad.
He responded: “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.”
The 31-year-old Canadian singer was previously linked to Kardashian, 45, after her split from Disick, when Bieber was 22 and she was 26.
A year after Reign’s birth on December 14, 2014, multiple sources alleged that the Poosh founder and the Grammy-winning singer were “hooking up.”
At the time, an insider claimed: “Justin started hanging out with Kourtney alone because she began going out more.
“He’s been showing her a good time.”
The source added that their connection first sparked in “late August, early September” and soon led to nights out together, including a visit to Universal Studios’ Halloween Horror Nights.
Bieber has maintained a close friendship with the Kardashian family for years, dating back to his 2010 Elle photoshoot with Kim Kardashian, which had a Mrs. Robinson-inspired theme.
During his rumored fling with Kourtney, sources claimed he frequently visited her home to spend time with her kids, who were said to “love” having him around.
Another insider revealed that Bieber got a “huge ego boost” from the alleged romance, explaining: “He’s used to being swooned over by young girls with nothing else going on. Kourt is a hot mom with a career.”
Although some speculated that Bieber was simply a rebound for Kardashian, he reportedly felt lucky that she was interested in him and even boasted about “how hot she is.”
The source added: “Even if she was using him to get back at Scott, he couldn’t care less.”
In 2016, Bieber addressed the dating rumors on The Bert Show, joking that he was “being used.” However, he had nothing but praise for Kourtney, saying: “For real, she’s great. I’ve known (the family) for years.”
Kourtney and Disick also share two other children—Mason, 15, and Penelope, 12.
In November 2024, Kardashian and her husband, Travis Barker, welcomed their baby boy, Rocky Thirteen Barker.
Meanwhile, Bieber became a father for the first time on August 23, 2024, when he and his wife, Hailey Bieber, welcomed their son, Jack Blues. The couple, who have faced ongoing speculation about the state of their marriage, have yet to publicly address the rumors.
In a past episode of The Kardashians, which aired last year, Kourtney playfully admitted she wasn’t sure where Reign got his comedic personality.
“He’s like a Jim Carrey,” she said in a confessional, reacting to Reign’s exaggerated expressions during a family trip to Australia.
Reflecting on his growing personality, she added: “I think he’s starting to get that sense of humor—just like his dad,” referring to Scott Disick.
She jokingly concluded: “Just what we need.”
