Reign Disick had something big to say when it comes to rumors that his father is Justin Bieber, following the singer’s brief fling with Kourtney Kardashian.

“No, he’s not. Bro, I swear, Justin Bieber is not my dad. Scotty … Scotty … Scotty is my dad,” Reign, 10, told viewers referring to Scott Disick. The priceless comment came during an Instagram Live session with stepsister Alabama Barker‘s boyfriend, Scooter Jackson, after Reign read a viewer comment claiming that Justin, 31, is his real dad.

The youngest of Scott, 41, and Kourtney’s three children then did some math.

“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,” Reign stated. He was born on December 14, 2014, when Justin was 20 years old.

Reign came along less than a year before Scott and Kourtney, 45, broke up in July 2015 after a nine-year relationship. In late 2015 after her split from Scott, reports began surfacing that the “Sorry” singer and the reality star were hooking up despite a 14-year age difference.

“Justin started hanging out with Kourtney alone because she started going out more,“ an insider told Us Weekly in December 2015, saying they had been hooking up for “months.”

“He’s been showing her a good time,” the source added.

In October 2015, Justin and Kourtney hit up the Hollywood hotspot The Nice Guy for dinner, and took in Universal Studios’ Halloween Horror Nights together, fueling rumors of a romance.

In a January 2016 appearance on The Ellen DeGeneres Show, an elated-looking Kourtney replied, “We’re friends,” when the host asked about where things stood with Justin.

“You’re smiling as if that maybe it’s beyond friends,” Ellen, 67, replied.

The Poosh founder continued to play it coy, saying, “I’ve been smiling this whole time since I’ve been sitting here.”

The duo never officially confirmed their romance. Justin went on to briefly date now-wife Hailey Bieber in early 2016 before tying the knot in 2018 on the heels of his split with Selena Gomez. Kourtney moved on to a three-year relationship with model Younes Bendjima in 2017.

Despite marrying Travis Barker in 2022 and welcoming a son, Rocky, in November 2023, Kourtney apparently still has concerns about Justin after all these years, especially after an old video surfaced of the “Baby” singer hanging out with Sean “Diddy” Combs as a teenager resurfaced in March 2024.

“Travis swears he’s not at all threatened by Justin, but he just finds it extremely disrespectful,” an insider exclusively told In Touch in October 2024. “Everyone knows [Justin and Kourtney] hooked up, whether Kourtney wants to admit it or not, and just from an ego perspective, Travis can’t handle the idea of people thinking she’s close to him again.”

“Travis is very possessive of Kourtney and doesn’t want her spending time with anyone else, really, let alone a guy she used to have a thing with,” the source added. “Ultimately, Kourtney is not going to disrespect Travis and go against his wishes, but at the same time, it is annoying to her. She wishes he would just get over it and act more mature. She has zero interest in Justin romantically. She’s just concerned for him like everyone else is and thinks he could use some support.”
