She's living her authentic self, and pissing everyone else off in the process.

Caitlyn Jenner grabbed her caffeine fix in Malibu this morning, and the transgender reality star was rolling solo per usual. That's unlikely to change anytime soon, because apparently the whole K clan is furious with her over her memoir Secrets of my Life and has cut her out of their lives.

"They are upset. This is the last straw. They're tired of being caught off guard. They want Caitlyn to be happy and share her experience, but they also wants her to be sensitive to Kris," a source dished to Us Weekly.

"They feel completely betrayed. Kim, Khloe and Kourtney have stopped talking to Caitlyn. As far as they're concerned, the relationship is done. She 's dead to them," another source dished to In Touch.

Apparently, they're none too pleased that the I Am Cait star discussed their late father Rob Kardashian and his involvement in the OJ trial, nor are they approving of the fact she's dragging their momager's name through the mud and blaming her for making her suppress her true feelings and identity.

In the latest round of cringeworthy leaks from her book, the Olympian explains how she's never been comfortable in sexual situations, even with then-wife Kris.

"My attitude is no different than it was in high school: I'm just not entirely comfortable with it," she wrote. Despite that, they still managed to conceive two children together. "Since - let's not kid ourselves - everyone wants to know, Kris and I had good and frequent sex at the beginning," she added.

As for her sex life post-transition?

"I don’t have the appetite for [sex], which is why the public’s obsession over whether I would [get gender confirmation surgery] is annoying to me. It hearkens back to this misperception that people transition because of their sexual desires," she explained. "A future female companion? I think about that. A future female sexual companion? Not happening, at least for now, and perhaps not even. A future male sexual companion? I have never had the inclination. But maybe that attitude might possibly change if I have the Final Surgery," she continued.

She's certainly not holding back, that's for sure!
