After Justin Bieber and reality star Kourtney Kardashian were spotting together at The Nice Guy in West Hollywood in October, rumors of the two hooking up on the down low ran wild.

Last weekend, speculations went into overdrive when Kourt was photographed leaving JB’s Beverly Hills hotel at 4 a.m. E! News’ Ken Baker called On Air with Ryan Seacrest Wednesday morning to weigh-in on the gossip with his insider knowledge, claiming the two are just friends.

“If you’ve seen Justin Bieber out in the wild and observed him as if he were a Discovery channel special … the guy flirts with every girl who is attractive,” he said. “This is like part of his persona, this is personality, this is what he does.”

Kourt split from longtime boyfriend Scott Disick in July after he was spotted in Monte Carlo with ex-girlfriend and L.A.-based celebrity stylist Chloe Bartoli. According to Ken’s understanding of  Kourtney’s personality, she is just having fun and has no intentions of getting in a relationship with a 21-year-old.

“Kourtney has been going out trying to have fun, trying to live her life,” he concluded. “It’s been a very difficult year with Scott and breaking up and the dramas there. I personally have no knowledge whatsoever of these two hooking up.”

He concludes, “She’s 36, he’s 21 — I don’t think she takes him seriously.”
