According to HollywoodLife.com, Kendall has asked her and Bieber's mutual friend Hailey Baldwin to convince the singer to cut off ties with her older sister. A source told the site that, "Kendall has been pressuring Hailey to talk to Justin about Kourtney, and how much drama it's causing between her and Scott [Disick]."
They added that, "Kendall thinks Kourtney and Scott still have a chance, but not as long as Justin's in the picture."
As interesting as all of that sounds, our friends at GossipCop.com say this whole Kendall-hates-Kourt-and-the-Biebs talk ridiculous. She is not trying to keep Bieber from seeing Kourtney. They were told by their insider that this is all "nonsense."
