They're in the same group of friends and socialize together all the time," the source explained. "They have been friends for years. Justin used to live next door to Kourtney and is still very close friends with the family. Kourtney and Justin being at a nightclub and leaving together is not a story."
As for Kourtney’s longtime love and the father of her three children, Disick, the only thing they are doing together these days is co-parenting and as for Bieber’s famous ex, Selena Gomez, she was recently spotted kissing The Weeknd.
