In a move that could add credence to the sexual harassment charges facing John Travolta, the "Pulp Fiction" star's long-time assistant has come forward with claims the actor is not only gay, but was also in a relationship with another man for six years.

RadarOnline cites a National Enquirer interview with Joan Edwards, credited by IMDb as having served as Travolta's assistant on films like "Urban Cowboy" and "Look Who's Talking" from 1978 to 1994, who claims that the actor and a male pilot named Doug Gotterba were lovers in the 1980s.

“I did everything for him, including taking care of his personal and professional schedules," Edwards is quoted by the Enquirer as saying. "Of course I knew he was gay. It never bothered me."

Of Travolta's alleged affair with Gotterba, who reportedly began working for the actor in 1981, Edwards added, "We both worked for John at the same time. Doug is a wonderful guy and we are still good friends. He told me that John was gay and they had a sexual relationship."

The publication also quotes Robert Britz, identified as Gotterba's post-Travolta boyfriend, who shed additional light on the alleged relationship:

"Doug told me right at the beginning of our relationship that he'd had a homosexual relationship with John Travolta in the 1980s. Doug said John was constantly grabbing at his genital area, but he put up with John's sexual advances because working for him was 'lucrative.'

I personally saw about two minutes of Doug's home video showing John Travolta sitting at the end of a bed with his shirt off. There were plates of food in front of him. The video appeared to be shot in a hotel room. Doug made it clear that it was very lucrative for him to be what he called John's 'personal right hand man' and homosexual partner."

Britz also adds that Gotterba eventually became turned off by John's "hairy body," as well as the actor's weight gain in between film projects.

Among those to jump to the defense of Travolta was his long-time friend supermodel Janice Dickinson. After noting that she "worships" the "iconic" star, Dickinson told RadarOnline: "If some queens took something the wrong way in a massage parlor, then that’s their f*cking fault!"

She then added, somewhat quizzically: "If you want to f*ck a chicken, go f*ck a chicken."

As HuffPost Celebrity reported last week, Travolta -- who has been otherwise tight-lipped about the scandal in recent weeks -- is currently the most sought-after star interview among top TV journalists including Diane Sawyer, Katie Couric and Matt Lauer.

"John is literally the most wanted person in the world right now,” one top TV executive is quoted as saying. “Everyone wants him, and he can literally pick who he wants to sit down with, if he decides to ever tell his side of the story at all."

Travolta, who is married to actress Kelly Preston, has been plagued by rumors about his sexuality for years.

"And I don't care if you're talking about things that are true, you're still talking about my personal life.. How about I go peek in your window, take what underwear you wore last night, whose husband you were f***ing, and shove that in the megaphone throughout your neighborhood? How does that feel?"

  • Kristin Stewart

    In 2009, gossip sites went wild with headlines that suggested the "Twilight" star was a lesbian. However, a closer look at Stewart's quotes <a href="http://www.telegraph.co.uk/news/celebritynews/6508461/Twilight-star-Kristen-Stewart-on-dating-Robert-Pattinson-We-are.-We-arent.-Im-a-lesbian.html" target="_hplink">reveals how she was actually responding to a question </a>over the nature of her relationship with co-star Robert Pattinson: <blockquote>"I've thought about this a lot. There's no answer that's not going to tip you one way or the other. Think about every hypothetical situation. 'OK, we are. We aren't. I'm a lesbian.' I probably would've answered if people hadn't made such a big deal about it. But I'm not going to give the finding an answer."</blockquote>

  • Jessie J.

    The British pop star, who is openly bisexual,<a href="http://www.huffingtonpost.com/2012/04/19/jessie-j-lesbian-rumors-biography-_n_1438372.html" target="_hplink"> faced allegations in an unauthorized biography</a> that she'd been ordered to withhold the fact that she was a lesbian by her record label. "Jessie might have been with boys in the past -- but she is 100 per cent gay," author Chloe Govan <a href="http://www.thesun.co.uk/sol/homepage/showbiz/tv/thevoice/4265487/Voice-coach-Jessie-Js-100-gay-but-bi-is-more-trendy.html" target="_hplink">wrote in an excerpt of the book</a>.

The singer <a href="https://twitter.com/#!/jessiejofficial/status/192975509381066752" target="_hplink">quickly took to Twitter</a> to deny the accusations, noting, "I'm really a lesbian?! Ha! Thanks for writing yet another boring untrue story."

  • James Franco

    The 21st century actor, artist, intellectual and overall "renaissance man" has believably played gay characters onscreen numerous times (most memorably as Harvey Milk's lover in the Oscar-winning "Milk"), but Franco <a href="http://insidemovies.ew.com/2011/01/05/james-franco-gay-roles/" target="_hplink">has downplayed the rumors</a> about his real-life sexuality.

    The "Jersey Shore" star reportedly hit back at housemates Nicole "Snooki" Polizzi and Jenni "JWoww" Farley after they speculated about his sexuality and hinted he might be gay in <a href="http://www.huffingtonpost.com/2012/02/07/jersey-shore-snooki-and-jwoww-bisexual-feminism_n_1255913.html" target="_hplink">an interview with HuffPost Gay Voices</a>. "Mike really ripped both Snooki and JWoww a new one," a show insider <a href="http://www.suntimes.com/entertainment/10514733-421/situation-to-snooki-and-jwoww-stop-hinting-that-im-gay.html" target="_hplink">told <em>The Chicago Sun-Times</a></em>. Noting that Sorrentino is concerned such comments could hurt his brand endorsements, which are focused on straight male customers, the source added, "He's extremely upset." In the interview, both JWoww and Snooki implied that despite his playboy reputation, Mike has questioned his own sexuality. "He brings it up," JWoww said. "He'll say, 'People think I'm gay and I don't know what they're talking about.'" Added Snooki: "He told me one time, '[All the talk is] making me wonder.'"

  • Bruno Mars

    Rumors that the pop star had come out of the closet began after CNN iReport -- a subsection of the media outlet comprising 'citizen journalists' from around the world -- <a href="http://www.towleroad.com/2012/04/bruno-mars-did-not-come-out-of-the-closet.html" target="_hplink">posted a since-removed story</a> that stated, "The famous pop-star Bruno Mars admits his homosexuality," which caused the Mars' name to trend on Twitter.

"It's tough because a lot of my friends in normal life, a lot of my friends in the entertainment business, and a lot of my friends in the wrestling business are gay," he told Wendy Williams. He continued, "Just to say something spiteful and hurtful, I don't get it...if it was true and I was gay, I'd embrace it, and I'd tell you guys about it and I'd celebrate it."

  • Tom Cruise

    Despite three high-profile marriages, the "Top Gun" star has been the subject of gay speculation for years.

As <em>People</em> <a href="http://www.people.com/people/article/0,,625389,00.html" target="_hplink">reported</a>, the suit was eventually dropped, and Davis eventually stated that Cruise "is not, and never has been, homosexual and has never had a homosexual affair."

  • Oprah Winfrey

    Speculation has swirled over the talk show queen's long-standing kinship with TV anchor friend Gayle King for years.

  • Vin Diesel

    When <a href="http://www.hollywood.com/news/Diesel_Slams_Gay_Rumors/3487636" target="_hplink">asked about the long-standing rumors</a> on his sexuality, the "Fast And The Furious" star proclaimed, "I was like, 'How could you say that? Why would you say that?'" He went on to note, "I'm not gonna put it out there on a magazine cover like some other actors. I come from the Harrison Ford, Marlon Brando, Robert De Niro, Al Pacino code of silence. I'm not gonna do that."

  • Kelly Clarkson

    Appearing on "The View," the pop star lamented the fact that she's never been in love and has difficulty dating, which <a href="http://www.huffingtonpost.com/2011/10/27/kelly-clarkson-denies-lesbian-rumors-on-the-view_n_1034814.html" target="_hplink">prompt many people to speculate that she's a lesbian</a>. "I'm from a small town so, like, everyone's married with children or about to have children," she said. "So it's a little hard when you go home and people are like -- and that's why people think I'm gay -- because they're like 'Why aren't you married?' And I'm like, 'it doesn't happen for everyone right off the bat.'"
