Kourtney Kardashian reportedly had a brief fling with the Canadian singer in 2015 after her split from Scott Disick. There are rumors that Kourtney's youngest child, 9-year-old Reign Disick, was fathered by Justin Bieber.
In October 2015, the media was buzzing with reports of a possible romance between Bieber and Kardashian. Speculation ran wild after they were spotted having a cozy dinner at The Nice Guy Restaurant in West Hollywood. Witnesses described them as "touchy feely," and the intrigue deepened when Kourtney was seen leaving Justin's hotel. Adding fuel to the fire, the "Peaches" singer posted a captivating black and white photo of Kardashian on his Instagram. The air was electric with whispers of their budding relationship.
A source told Us Weekly at the time, “Justin and Kourtney have been hooking up since late August, early September.” The pair HAD been seen at Universal Studios in October and posted a photo together wearing matching 3D glasses.
Another source claimed, “Justin bragged to friends recently that he has been hooking up with Kourtney Kardashian. Oh yeah, that's definitely happening and has been for some time now.”
“Kourtney is great. Justin thinks it's cool that she is older and hot. She isn't clingy and has her own life. There are no bad consequences for Justin to hook up with her. She is very easy going and just makes it fun for him to be around her,” another source said.
Justin addressed the rumours in 2015, telling The Bert Show: 'I'm being used, man. What can I say?...No, no, but for real, she’s great. I've known [the family] for years.' When host Bert Weiss asked, “Anything there?” the singer replied, “Nah, we’ll leave it at that.” And during an appearance on The Ellen Show, Kardashian blushed and grinned while insisting that she and Bieber were “just friends.”
