Kougar Kourtney’s Sisters ‘Totally Creeped Out’ By New Barely Legal Boyfriend

Kourtney Kardashian has sunk her kougar klaws into 20-year-old model Luka Sabbat and RadarOnline.com has exclusively learned that her sisters are “totally creeped out” because he is half her age!

According to a Keeping up with the Kardashians confidante, “Luka was at Kylie Jenner’s 21st birthday party and knows Kendall too.”

“He is younger than both of them and the worst part is that Kourtney thinks that it makes her hotter.”

And it's not only Kendall and Kylie that are irked by Kourtney’s new fling.

“Kourtney told Kim and Khloe that she will never date anyone older than half her age and Khloe told her that she really needs to grow the f**k up,” the insider told RadarOnline.com exclusively.

“Kim thinks she is just starving for attention and cannot believe that she would go for Luka.”

So what does ex Scott Disick, who is dating 20-year-old Sofia Richie think?

“Scott is convinced that she is trying to one up him with a 20-year-old. No one approves of this barely legal cling-on”

As RadarOnline.com previously reported, although the mother of three has been spotted out with Sabbat, she is also still hooking up with on-again, off-again previous boytoy, Younes Bendjima, 26!
