Kourtney Kardashian's Son Reign Sets The Record Straight On Justin Bieber Paternity Rumours

Kourtney Kardashian's son Reign has dismissed rumours suggesting Justin Bieber is his real dad.

' The Kardashians ' star is mother to Mason, 15, Penelope, 12, and Reign, 10, with her ex-boyfriend Scott Disick as well as baby Rocky with husband Travis Barker, but Reign has long faced gossip about his parenthood due to his physical similarities to pop star Bieber - and now the youngster has shrugged off the speculation for good.

During an Instagram Live video with his step-sister Alabama Barker's boyfriend Scooter Jackson, Reign was asked about the rumours and he said: 'No, he's Bieber not my dad. 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.'

Reign was born in December 2014 - a year before his parents split in 2015. After the break-up, Kourtney was rumoured to have dated Bieber - who is 14 years her junior - but the relationship was never publicly confirmed and the singer later insisted there was nothing romantic going on between them.
