19-year-old Kendall Jenner has reportedly found herself at the center of some shocking rumors regarding an alleged affair with her sister Kourtney’s longtime boyfriend, Scott Disick.

These recent rumors may be the last straw for the model, who has been distancing herself from “Keeping Up With The Kardashians” since launching her career in fashion.

“Kendall is now questioning whether or not she should remain on the show,” a source exclusively told HollywoodLife.

The insider added, “She doesn’t want to be known as a reality star, she wants to be taken seriously.”

Despite Kendall’s desire to no longer be a part of KUWTK, momager Kris Jenner isn’t ready to let her go just yet.

“Kris of course is like, ‘No way, don’t be silly. There is no such thing as bad publicity.’ But Kendall is not happy about this one bit,” the source added.

The insider continued, “She’s really having second thoughts about sticking with the show. She wants to express all this on Twitter but was told by Kris to just minimize it and make light of it.”

Kendall is reportedly “mortified” over the recent rumors.

“Kendall says this whole story makes her look cheap and it’s not the kind of publicity that she wants. Her sisters, including Kourtney, are telling her not let it bother her, but she is just beside herself,” explained the source.

The insider added, “She would never cheat with someone let alone with her own sister’s guy, and plus Scott’s not even her type. She thinks it’s gross.”

Although Kendall is taking the rumors seriously, sister Khloe Kardashian is clearly not, according to the NY Daily News.

“I’m really pissed about this whole @Kendall Jenner and @ScottDisick thing!!,” the KUWTK jokingly tweeted on Wednesday.

She added, “Scott, I thought it was you and I that was having an affair!!”
