Lawsuit Claims John Travolta's Son is Elvis Presley's Great-Grandchild

Priscilla Presley hits back at new claims that her granddaughter Riley Keough is the biological mother of John Travolta's youngest son.

Billboard magazine obtained court records Thursday pertaining to an ongoing $50 million lawsuit against Priscilla by two former business associates. The amended complaint by Brigitte Kruse and Kevin Fialko is part of their original claim that Priscilla committed, "fraud, breach of contract and other civil misdeeds."

The plaintiffs claim that Travolta and his late wife, Kelly Preston, used eggs donated by Elvis Presley's granddaughter Keough to conceive their now 15-year-old son Benjamin, in exchange for an old Jaguar car and up to $20,000 in payment.

"The lawsuit also claims that Michael Lockwood, who was married to Lisa Marie, provided the alleged information to Kruse and Fialko."

"There had been talks about an egg donation from Lisa Marie Presley, who would have been in her early 40s in the early 2010s, to Travolta's wife, the late Kelly Preston, lawyers for Kruse and Fialko said," according to NBC News.

"But that deal went south as Travolta did not want 'eggs with heroin' on them and they orchestrated a deal, where Riley Keough gave her eggs to Travolta so that Kelly could give birth to their son, Ben Travolta," Kruse and Fialko allegedly also stated.

"Riley was given an old Jaguar and paid between $10,000 — $20,000 for the deal," according to the plaintiffs.

Travolta and Preston share three children, Benjamin Travolta, Ella Bleu Travolta, 25, and the late Jett Travolta, who died in 2009 at age 16. Preston gave birth to all three children.

Priscilla’s lawyers Marty Singer and Wayne Harman reportedly told Billboard, "These recent outrageous allegations have absolutely nothing to do with the claims in this case. The conduct … is shameful, and it absolutely will be addressed in court."

Previous claims made by the plaintiffs allege that Priscilla took her daughter Lisa Marie off life support against Lisa Marie’s wishes, and that Priscilla pushed Elvis to his death.
