Kourtney Kardashian’s son Reign has spoken out about the conspiracy theory that his biological father is Justin Bieber, not Scott Disick.
Fans have speculated for years about the 10-year-old’s true paternity, but now Reign himself has addressed the rumours.
While appearing on his stepsister Alabama Barker’s boyfriend Scooter Jackson’s Instagram Live, a viewer asked if Bieber, 31, was Reign’s dad, which he then roundly denied.
Reign said: ‘No, he’s not. Bro, I swear, Justin Bieber is not my dad. Scotty…Scotty…Scotty is my dad.’
The pre-teen continued: ‘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.’
The pop superstar – who has been married to wife Hailey since 2018 and is the father to Jack Blues Bieber – was briefly romantically linked to Kourtney in 2015, following her split from Disick.
However, Reign was born December 14, 2014, a full year before the pair were rumoured to be ‘hooking up.’
‘Justin started hanging out with Kourtney alone because she started going out more,’ an insider told Us Weekly, at the time. ‘He’s been showing her a good time.’
‘They have hooked up a few times, including recently,’ an additional source told People magazine. ‘It happens in LA.

‘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.’
Kourtney, who was 36 at the time, was linked to the 22-year-old Love Yourself singer a few months after her split from Scott, who is the father to her three children: Penelope, Mason, and Reign.
‘I’m being used, man. What can I say?’ Justin joked when asked about their rumoured romance on The Bert Show radio show a few months after the rumours first started to swirl.
He also posted an Instagram embracing a woman against a car, and many fans believed it was Kourtney.
This isn’t the only rumour about Kourtney’s family to be shut down recently, with theories that her 15-year-old son Mason Disick secretly fathered a child swirling online back in March.

Kourtney denied the social media theories that Mason had a daughter named Piper in 2024, writing on social media: ‘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. They are not,’ Kourtney wrote.
She continued: ‘Mason does not have a child. These accounts that pretend to be him are definitely not. They are FAKE. My son really values his privacy, and I am asking all media to please be respectful: he is a kid with feelings and a beautiful life ahead of him.’

The reality star pleaded with people to ‘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,’ she concluded.
The rumours arose when an Instagram account – claiming without evidence to be Mason’s ‘secret’ page – posted photos of a baby girl.
