The author of a book called You’ll Never Spa In This Town Again is suing John Travolta and his attorney, Marty Singer, for libel for allegedly hurting his chances to sell the controversial book about Travolta’s alleged sexual encounters with men in spas.

Robert Randolph claims a letter drafted by Singer and published by Gawker.com hurt his credibility by repeating these alleged lies:

• a brain injury affected Randolph’s ability to recall past events
• the book is filled with “phony tall tales”
• Randolph had been to a mental institution

Randolph claims Singer’s attack affected his ability to sell the book. He’s asking for a jury trial and suing for unspecified damages.

Singer calls the lawsuit “absurd.”  He goes on to say, “The suit is based on a privileged communication, and it will promptly be thrown out by the court. “

Travolta’s rep released this statement to RumorFix,:

“To evaluate the credibility of Robert Randolph and his ridiculous lawsuit one need look no further than his own statements published on his website stating that he sustained “permanent brain damage” and had to “retrain” his brain.  Randolph also claimed on his website that after he was beaten and sustained brain damage at a spa, he allegedly returned to the same spa months later, and that the same assailant was there and supposedly attacked him for a second time.

Mr. Travolta will aggressively defend himself against this lawsuit and expects to be fully vindicated when this meritless case is dismissed.”
