The truth hurts.

Kourtney Kardashian is reportedly none too happy about being the only K sister left off Maxim's Hot 100 list, and she's blaming her momager for the oversight.

"[Kourtney] is super upset about this because she thinks she is such a huge star! Kourtney just doesn’t understand how Maxim could leave her off the list, but let sisters Kim, Khloe, Kendall and Kylie on. Kendall and Kylie haven’t been famous as long as Kourtney has so she is just really baffled by this," a source dished to Radar.

Rather than letting the snub roll off her back, the 39-year-old is pointing the finger at Kris Jenner.

"She is blaming Kris for not giving her her own company like she did all of her other daughters. But she is also blaming herself for thinking she is such hot s**t when, in fact, she isn’t," the source added.

If this is her biggest problem, we don't feel sorry for her at all!
