Kourtney Kardashian and Justin Bieber have been secretly hooking up for 'FOUR' months

Getting their flirt on: Justin and Kourtney

Kourtney Kardashian and Justin Bieber's rumoured romance appears to be a lot more serious than first thought.
The 36-year-old reality beauty and the pop star first sparked dating speculation last month after they were spotted at a number of West Hollywood hot spots.
But according to a US magazine, the pair's flirtation goes back a lot farther than November.
“Justin and Kourtney have been hooking up since late August, early September,” a source told Us Weekly.
While another source added to People magazine: "It's been a deep flirtation for months. He's obviously close to the family, and Kris is obsessed with him."

 

However, they added that it's not about to become a full-blown relationship any time soon.
"It's just one of those things where it makes Kourtney 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."

 

And what does Scott Disick make of it all, especially after the pop star appeared to taunt him with a steamy Instagram picture which was captioned 'Lord knows'?
“He’s had so many stories about him recently, he has no reason to be pissed,” the source told Us Weekly. “He feels like he has to take the humiliation.
“Scott feels she’s doing this to get back at him and get revenge. He feels he has to take it and can’t say anything after all he did to her, but he thinks it’s dumb and immature.”
