Did Kendall Jenner and Travis Scott really sleep together behind Kylie Jenner’s back? This is what a new tabloid report claims. The fashion model and the rapper reportedly had an affair and Forbes’ youngest self-made billionaire is furious about it.

Celebrity magazine Life & Style ran a scandalous story involving sisters Kendall and Kylie and the latter’s baby daddy, Scott, in its latest issue. According to its report, Kendall and Travis apparently had sex back in 2015 and Kylie just learned about this recently, so she’s very mad at her older sister.

A supposed source said that Kylie is having a tough time because she’s learned of this betrayal just after she found out that ex-best friend Jordyn Woods also had an affair with her man. The source alleged that this is another “heartbreaking” moment for the Lip Kit mogul.

“When Kylie found out Kendall hooked up with Travis, she went ballistic,” the source was quoted as saying by the magazine. “Kylie found provocative photos of Kendall and Travis and hit the roof. She told friends that her sister was now dead to her.”

The source also claimed that even though Kendall and Travis didn’t develop a serious relationship, they did have a brief fling back when the rapper’s career was just taking off. The magazine’s tipster added that Kylie is feeling so “alone” right now and she suspects that Travis is still into her sister.

However, all of the claims made by Life & Style’s source have been debunked by Gossip Cop. According to the fact-checking website, the story was not only suspicious, it’s also confirmed to be totally bogus. Upon reaching out to Kendall’s spokesperson, the outlet found out that the narrative is “absolutely false.” The fashion model and the rapper never hooked up.

There’s also no reason to believe that Kendall and Kylie are fighting because the two are said to be collaborating for a new cosmetics line. In a recent Instagram Live, Kylie revealed that she’s working with Kendall on a new project but the details of which will remain a secret for now. This wouldn’t be their first collaboration since they actually launched a clothing line for PacSun back in 2013.
