 Kourtney Kardashian -- Denies Hooking Up with Bieber ... But It's True 
 
 EXCLUSIVE 
 
 Kourtney Kardashian is flatly denying she's hooking up with Justin Bieber, but our sources say Bieber and company are laughing, because she is. 
 
 Sources close to Bieber tell TMZ the fling started in October when they ran into each other at The Nice Guy in West Hollywood. 
 
 Our source says Kourtney flirted and Justin decided to make a move, and they've hooked up a couple of times since then ... the last being this past weekend when Kourtney left Justin's Beverly Hills hotel at 4 AM. 
 
 Kourtney has been grilled like a cheeseburger by her family and she's insisted all she's done with Bieber is hang out with groups of people in the hotel. 
 
 Justin and company beg to differ ... as one source says, "He's single, she's single and they're just having a good time. Nothing serious." 
 
 BTW ... can't blame Kourtney for denying it, since her younger sister Kendall and Justin hooked up too.

– Now that fairly reputable celeb magazine People has covered it, it must be true—though still disturbing on a number of levels: Justin Bieber and Kourtney Kardashian are having a fling. The 21-year-old and the 36-year-old have been spotted out and about recently (People reported Monday that they had been "inseparable" and "super touchy-feely" at an LA club Friday night), and now sources tell the mag why the Biebs is so into it. "He has had a huge ego boost from hooking up with Kourt. It's been going on for a few months," a source says. "He is used to being swooned by young girls that have nothing else going on. Kourt is a hot mom with a career." Some may say Kardashian is simply rebounding from her ex, the father of her kids, Scott Disick, but Bieber doesn't care: "He more thought, 'Wow,' and couldn't believe that she would go for him," the source says. Another insider tells People that Kardashian basically feels the same way: "It's just one of those things where it makes Kardashian feel good about herself. It's not serious at all. This young guy is into her, he thinks she's hot and she's older. She just wants to have fun." TMZ also says the Kardashian-Bieber hookup rumors are undoubtedly true. (But apparently not serious enough to stop Bieber from hanging out with a boatload of models.)
