Khloé Kardashian and Scott Disick aren't brother and sister by blood but that doesn't stop them from having a sibling bond. The "Keeping Up With The Kardashian" stars are practically family. In fact, their bond is so close Disick is reported to have opened up about what he hates about Khloé.

A source revealed Disick's supposed true feelings to Us Weekly. “He’s always looked at Khloé as a sister," the insider explained, "and he’s seen her been burned by men over the years and he hates that for her.”

The 36-year-old, who recently celebrated his birthday with girlfriend Sophia Ritchie and Kourtney Kardashian, Khloé's sister and the mother of his three children -- Mason, 9, Penelope, 6, and Reign, 4 --- is not a fan of bad things happening to the "Revenge Body" host. Especially since he believes she is an "unbelievable" human being.

During part one of the two-part "KUWTK" season finale that aired on E! on Sunday, Disick expressed his admiration for the 34-year-old mother of True. After Khloé had spoken to her child's father, Tristan Thompson, and the cheating allegations against him, the NBA baller allegedly threatened to hurt himself. Disick, who was seated next to the Good American co-founder, was shocked by Khloé's response.

"The fact that Khloe's sitting here heartbroken, but still worrying about Tristan's feelings and the possibilities of him being upset or possibly hurting himself, I mean, it just goes to show that Khloe is an unbelievable person that loves so hard and so much and only wants good," he said on the episode, according to Entertainment Tonight.

Disick added, "And somehow she just keeps getting the short end of the stick and it's unfair and it's hurtful. It's really hard for me to sit and watch."
