Robert Randolph, the author of You’ll Never Spa in this Town Again: A True, Steamy Celebrity Tell-All, is reportedly suing actor John Travolta and his attorney Marty Singer, alleging that the two are trying to “spread lies about his mental health in order to diminish his credibility.”

In his book, which he self-published in February under the imprint Bluff Place Publishing, Randolph claims to have seen Travolta, among other celebrities, in steamy spa scenes.

TMZ has more: “A rep for Travolta has issued a statement … saying, ‘The lawsuit filed by Robert Randolph is absurd. The suit is based on a privileged communication, and it will promptly be thrown out by the court.’”

The book’s Facebook page claims: “…on the most shocking day of all, January 30, 2007, the author witnessed Travolta with his son, Jett, and his nanny, Jeff Kathrine, with him at the Century Spa in Los Angeles while he was up to his usual tricks. We have the photos to prove it!”
