Kourtney Kardashian Denies Hooking Up With Justin Bieber

Sources close to Justin Bieber have said that Kourtney Kardashian and Justin are seeing each other and Kourtney Kardashian flatly denying she's hooking up with Justin Bieber.

The fling they said started in October when the two ran into each other at The Nice Guy in West Hollywood. A source said that Kourtney flirted and Justin decided to make a move, and they've hooked up a couple of times since then as they were last seen together 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”.
