Kendall Jenner Reportedly Broke Up With Julian Brooks — Report

Kendall left her admirer’s hearts broken after she hooked up with Sierra Canyon School classmate Julian in May 2012. But they can now breathe a sigh of relief — Kendall is back on the market.

Reports surfaced that Kendall had dumped the University of Nevada football player after friends confirmed Kendall’s biggest fear — he’s a cheater.

“He would disappear for days and not answer Kendall’s text messages,”  sources told Star magazine.

Kendall reportedly couldn’t handle the rumors any longer and decided to end their almost-two-year relationship. So sad — but we’re glad she stood up for herself!

The cheating rumors got to be too much, though, and Kendall “couldn’t live with the doubt,” the source alleges.

Julian Brooks: Kendall Jenner’s Ex-Boyfriend — And Athlete

Julian is a star athlete playing safety for the Nevada Wolf Pack. And looks-wise?  He towers over the 5’10 Kendall standing at 6’3. The college athlete also has a beanie line, “Brooks,” that Kendall had been seen wearing on Instagram.

He sounds like a fun, cute and ambitious guy — if only he hadn’t cheated on Kendall! However, we know that Kendall’s sisters will have her back for a shoulder to cry on during tough times like these!

What do YOU think, HollywoodLifers? Is Kendall better off without Julian?
