Kourtney Kardashian’s son Reign has hit back at rumors that suggest Justin Bieber is his real dad.

The 10-year-old boy responded to the wild rumors when he joined his stepsister, Alabama Barker’s boyfriend, Scooter Jackson’s Instagram Live.

A viewer asked the kid if Bieber is his real father, and Reign clarified that Scott Disick is his father.

He 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,” he explained.

Rumors of Bieber being Reign’s father took hold a year after he was born on December 14, 2014. Multiple sources claimed that the baby hitmaker and The Kardashians star were dating.

A mole said at the time: “Justin started hanging out with Kourtney alone because she started going out more. He’s been showing her a good time.”

The mole explained, “He is used to being swooned by young girls that have nothing else going on. Kourt is a hot mom with a career.”

The tipster even claimed that Bieber felt lucky “she would go for him.”

They added: “Even if she is using him to get back at Scott, he couldn’t care less.”

Kourtney Kardashian and Scott Disick also share son Mason, 15, and daughter Penelope, 12.
