Kourtney Kardashian Responds to Rumour That Justin Bieber Fathered Her Son Reign

After a wild fan theory resurfaces online, both Kourtney Kardashian and her 10-year-old son Reign Disick address the speculation—firmly and humorously.

April 5, 2025: Kourtney Kardashian is well aware of the internet’s wilder rumours — including one that claims pop star Justin Bieber is the father of her youngest child, Reign Disick.

Her reaction? Total amusement.

According to a source quoted by Us Weekly, Kourtney “doesn’t give any heed to the reports that Justin is Reign’s father,” adding, “She thinks it’s ridiculous and laughs that people online would even believe that.”

Even young Reign has caught wind of the chatter. In a recent Instagram Live shared by Alabama Barker’s boyfriend Scooter Jackson, the 10-year-old took the mic to set the record straight:

“No, he’s not. Bro, I swear, Justin Bieber is not my dad,” he said, before clarifying, “Scotty … Scotty is my dad.”

For those still curious: Reign is Kourtney’s third child with ex Scott Disick. The two dated on and off for nearly a decade before splitting in 2015. They also share son Mason (15) and daughter Penelope (12).

And Reign, proving he’s got both humor and brains, even added:

“I think Justin Bieber was 16 when I got born. I don’t think my mom would do that.”

For the record, Kourtney was 35 when Reign was born — and yes, that makes the conspiracy not just implausible but impossible (and illegal).

Rumors of a romantic link between Kourtney and Bieber did circulate briefly in 2015, after her breakup with Disick. But even that short-lived fling — if it even happened — was years after Reign was born.

This marks the second bizarre parenting-related rumor Kourtney has tackled this year. In March, she publicly denied false speculation that her eldest son, Mason, had a child of his own.

“He is a kid with feelings and a beautiful life ahead of him,” she wrote at the time. “Please stop spreading false narratives.”

Her message is clear: Kids are off-limits.
