Riley Keough ‘Devastated’ Amid Alleged Revelation She’s the Biological Mother of John Travolta’s Son (Exclusive)

Riley Keough is reeling amid the alleged revelation that she’s the biological mother of John Travolta’s youngest son Ben, 15 — not Kelly Preston — and it’s plunged their respective families into a world of turmoil, Globe has learned.

“Riley is devastated to be dragged into something like this,” says a source. As is Travolta, 71. “John is one of the most private people in Hollywood [so] having his son’s origins debated in public is deeply upsetting,” the source adds.

As Globe has previously reported, Priscilla Presley’s former business associates Brigitte Kruse and Kevin Fialko made the shocking claim in an amended complaint to their $50 million breach of contract suit against her son — and Riley’s uncle — Navarone Garibaldi Garcia.

In the lawsuit, the pair claim Lisa Marie Presley’s ex-husband Michael Lockwood told them that Travolta’s late wife, 57, wasn’t able to bear her own children and that the Grease star “orchestrated a deal” following the 2009 death of their son Jett, 16, where Keough, 36, would give her eggs to the couple — who also share daughter Ella, 25 — so that Preston could give birth to Ben.

“These recent outrageous allegations have absolutely nothing to do with the claims in this case,”  Presley’s attorneys, Marty Singer and Wayne Harman, told TMZ of the latest claims. “The conduct of Kruse, Fialko, and their new lawyers (they are on their fourth set of attorneys) is shameful, and it absolutely will be addressed in court.”

However, Kruse and Fialko don’t seem to be backing down. Their attorney, Jordan Matthews, said in a statement to The National Enquirer: “Any contention that our allegations are ‘outrageous’ or ‘cross an ethical line’ is nothing more than a crafty attempt to bend the facts and create a false narrative.”

“Priscilla and Riley are not prepared to dignify the claims by responding publicly and will only speak through their lawyers, but that doesn’t mean it isn’t taking a huge emotional toll,” says Globe’s source, noting that neither Keough nor Presley, 80, have any control over what could come out next.

“These people can accuse them of anything and it will end up getting traction, whether it’s true or not,” the source explains. “They are clearly hell bent on humiliating Riley and Priscilla any way they can. Whether it’s to force a massive settlement or to settle scores isn’t as clear.”

One thing is certain, though. “Whatever the motive, they are succeeding in causing serious anguish,” says the source.
