John Travolta is facing a new lawsuit amid claims that he tarnished the reputation of an author by trying to sell a book exposing seedy details about his alleged sexual exploits with spa workers.

Robert Randolph has alleged in a new lawsuit that Travolta and his attorney, Marty Singer, made false claims about his mental health in a bid to bring the writer’s credibility into question.

Randolph is suing both the actor and his lawyer for unspecified damages.

Randolph, in his book ‘You’ll Never Spa in This Town Again’, made explosive claims that he witnessed Travolta engaged in sexual intercourse with other men at various bathhouses.

According to TMZ.com, Randolph was also sexually involved with the actor.

The writer claims as the book was coming out, Travolta and Singer made false public allegations that he had spent time in a mental institution and was not a reliable source.

Randolph claims the PR tactic proved successful and retailers were put off from putting his work on shelves.

Randolph’s suit follows a string of sordid claims about Travolta’s sexual orientation.

According to reports, former pilot Doug Gotterba is "considering" writing a tell-all book about their alleged six-year affair in the Eighties - before the actor’s marriage to Kelly Preston in 1991.

The simmering scandal heated up last month, when the Hollywood A-lister was hit with two lawsuits from masseurs claiming the actor made sexual advances towards them during massages, but one claim was later withdrawn.
