Kylie Jenner's Twitter Rant: 15-Year-Old Slams Claims Bruce Jenner Is Not Her Biological Father

Kylie Jenner is fighting back after a tabloid claimed Bruce Jenner is not her biological father.

The 15-year-old took to Twitter to slam magazine editors for publishing such hateful stories about her family, posting over 20 tweets about how it should be illegal to print false rumors about a minor.

“It sickens me how editors of a magazine can proudly write a story denying that a 15 year olds father is actually hers,” Kylie began, continuing, "Yes, my father is my father and no my parents aren’t getting a divorce. You guys can’t believe any of these magazines.. It’s all bullsh*t.”

Kylie, who is the youngest of Bruce and Kris Jenner's daughters -- Kendall is 17 -- went on to say that tabloids "disgust me" and that they're all "pathetic." She also noted that all the Kris and Bruce divorce reports are "getting old."

As for her final thoughts on the topic, Kylie says she's ready to take legal action. "Im gonna find out if this is legal.. like it shouldn't be legal to publish harmful false information about a minor...should it? lol," she wrote, adding, "& it shouldn't be legal to post false info in general! can't we sue or something hahaha."

And Kylie wasn't the only one who was proud of her Twitter rant against "cyber-bullying." Her sisters Kourtney and Kim Kardashian stood up for her, congratulating their sibling on calling out the lies.

"That was some rant @KylieJenner but I just want to say that I am proud and honored to have you as my sister. What a well spoken young lady!" Kourtney tweeted, with Kim adding:
