Kourtney Kardashian is said to be ‘livid’ after son Reign addressed a bizarre 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 were left shocked when Reign addressed the rumours himself on Instagram.
However, the move reportedly left his famous mum reeling, and fearing how to protect him from social media.
An insider claimed: ‘Kourtney has never talked to Reign about the rumors and she would imagine this was the first time he had ever heard them.
‘Kourtney was livid. She told him that there are so many silly rumors about the family and that he is not to believe anything. She tries to keep her kids away from this stuff but as they get older she is unable to as easily.’
‘Kourtney doesn’t like when Reign is online and would rather him not talk about anything that happens with the family or answer random rumours,’ they added to the Daily Mail. ‘If he continues to do it, it is only a matter of time before he says something damaging.
‘Kourtney wants to act on this now before it is too late. She has talked to him about her concerns. She knows he doesn’t realize the impact he has and people will be watching his every move. He could get in trouble.
‘Kourtney will ban him from social media if he continues to act up.’
Things kicked off when Reign popped up on an Instagram Live with Scooter Jackson, who is currently dating the youngster’s stepsister, Alabama Barker.
A viewer took the opportunity to ask if Justin, 31, was his 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.
‘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 Scott.
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 speculation 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.
‘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.
Metro has contacted Kourtney’s reps for a comment.
