John Travolta Sued By Author of Spa Sex Book

John Travolta is being sued by the author of “You”ll Never Spa in This Town Again” — an author who claims Travolta and his lawyer publicly trashed him.

Robert Randolph wrote in his book about alleged homosexual encounters at various bathhouses.

Randolph claims in his lawsuit which was just filed in L.A. County Superior Court … Travolta and his lawyer, Marty Singer (pictured above), publicly spewed lies about him to blow up his credibility.  Randolph says Travolta and his lawyer made false statements questioning his mental health and his alleged admission to mental institutions.

Randolph is suing both Travolta and Singer for unspecified damages.
