Kardashian, 37, and Bieber, 22, first sparked dating rumors last October when the two were spotted at The Nice Guy in West Hollywood, California, followed by a trip to Universal Studios Hollywood's "Halloween Horror Nights." Since then, Kardashian also appeared at a few of the "Sorry" singer's impromptu Los Angeles shows, with an eyewitness claiming they appeared "inseparable" at the time. Last December, Bieber even attended a joint birthday party for Kardashian and Disick's two sons, Mason, 7, and Reign, 2.
But after the rumored pair was seen hanging out again on Saturday, this time at celeb hot spot The Peppermint in Los Angeles, a source put the rumors to rest, confirming to ET that "Kourtney and Justin are not hooking up."
"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 Kardashian's on-again, off-again relationship with Disick? According to the source, nothing romantic is happening there, either. The amicable exes, who also share 4-year-old daughter Penelope, are simply co-parenting "and doing a great job at it," the source added.
"Kourtney and Scott are not back together or even at the point of trying to make things work," the source told ET. "Kourtney is happy being a parent right now and that is her No. 1 interest right now. She's not interested in being in a relationship with anyone."
"[Kourtney and Scott] have a wonderful relationship and are doing an amazing job at being good friends for their kids," the source continued. "There is nothing more to it than that right now."
"Scott is in a great place right now," the source dished. "He has toned down his partying and has done a really good job of staying in control. Everyone is really proud of Scott for sticking to his word and calming down."
