Justin and Hailey officially dated for the first time in 2016, not long after the rumors that he had been hooking up with Kardashian.
“Hailey has every reason to feel threatened,” a source told Hollywood Life in August 2018. “Now that she’s [Kourtney] single, she’d go after Justin again in a heartbeat.”
There were rumors that the singer also hooked up with Kendall Jenner
Kourtney Kardashian isn’t the only member of her famous family that Justin Bieber is rumored to have hooked up with. There has also been speculation that the “Stay” singer had a fling with Kardashian’s younger half-sister, Kendall Jenner.
