The fun began when the reality star and pop singer first hooked up in late August, early September, according to another insider. Their first public outing together which seemed innocent at the time was at Hollywood lounge, The Nice Guy in October for dinner followed by a trip to Universal Studios’ Halloween Horror Nights.
The “Sorry” crooner first became friends with the family in 2010 when he posed with Kourtney’s famous younger sister Kim Kardashian for a Mrs. Robinson inspired Elle shoot.
Since then, he’s been out partying with Kendall and Kylie Jenner and has turned to Kim’s hubby, Kanye West, for career advice. Plus, Bieber’s former tour manager Corey Gamble is now dating Kourtney’s mom, Kris Jenner. Double date soon?
Bieber also loves spending time with Kourtney’s kids; Mason, 6, Penelope, 3, and Reign, 12 months.
“He actually goes over a lot to see her kids, and they love him,” the source says of Bieber.
