The teenage 'Keeping Up With the Kardashians' has taken to her Twitter page to deny reports claiming the celebrated Olympian is not her real father.
"It sickens me how editors of a magazine can proudly write a story denying that a 15-year-old's father is actually hers. Yes, my father is my father, and no my parents aren't getting a divorce...," Kylie wrote.
"And even though I don't let these stories get to my head, imagine (yourself) at 15 and someone telling you your father isn't your father," the youngster said while threatening to take a legal recourse.
She was supported by her half-sisters Kourtney Kardashian and Kim Kardashian.
Earlier, reports claimed that Khloe Kardashiam-Odom was the love child of Kris and Todd Waterman, something the family denied later.
