Kendell Jenner has had rumours swirling about her sexuality for as long as she's been in the spotlight. Some people thought that Kendall Jenner and Cara Delevingne's abrupt ending to their friendship was actually them breaking up from a more serious relationship.
In an interview with Vogue, she addressed why the rumours exist:
I think it’s because I’m not like all my other sisters, who are like, ‘Here’s me and my boyfriend!
She also got to the point and addressed her sexuality:
I don’t think I have a bisexual or gay bone in my body, but I don’t know! Who knows?! I’m all down for experience—not against it whatsoever—but I’ve never been there before,
To answer your question: I’m not gay. I have literally nothing to hide. I would never hide something like that.
