"20/20" ADDS REPORTS TO PREVIOUSLY-ANNOUNCED TRAVEL MYTHS, AIRING FRIDAY, DECEMBER 14 ON ABC

* Brian Ross' Exclusive Interview with Victim Who Claims Gang-Rape Cover-up by U.S., Halliburton/KBR in Baghdad

* Britney Spears' Newest Video Turns the Tables on the Paparazzi Who Follow Her Every Move � "20/20" to Air Never-Before-Seen Footage from Video

A Houston, Texas woman says she was gang-raped by Halliburton/KBR coworkers in Baghdad, and the company and the U.S. government are covering up the incident. In an exclusive interview with ABC News Chief Investigative Correspondent Brian Ross, Jamie Leigh Jones, now 22, says that after she was raped by multiple men at a KBR camp in the Green Zone, the company put her under guard in a shipping container with a bed and warned her that if she left Iraq for medical treatment, she'd be out of a job. "Don't plan on working back in Iraq. There won't be a position here, and there won't be a position in Houston," Jones says she was told. In a lawsuit filed in federal court against Halliburton and its then-subsidiary KBR, Jones says she was held in the shipping container for at least 24 hours without food or water by KBR, which posted armed security guards outside her door who would not let her leave. Finally, Jones says, she convinced a sympathetic guard to lend her a cell phone so she could call her father in Texas. The report will air on "20/20," FRIDAY, DECEMBER 14 (10:02-11:00 p.m., ET) on the ABC Television Network.

According to her lawsuit, Jones was raped by "several attackers who first drugged her, then repeatedly raped and injured her, both physically and emotionally." A spokesperson for the State Department's Bureau of Diplomatic Security told ABC News he could not comment on the matter. Halliburton, once headed by vice president Dick Cheney, has won more than $16 billion in contracts with the U.S. government for work in Iraq and Afghanistan between 2004 and 2006. It spun off its subsidiary, KBR, in April. Jones is suing both companies in civil court; Halliburton says she has improperly named it as a defendant.

In a statement, KBR said it was "instructed to cease" its own investigation by the U.S. Government authorities "because they were assuming sole responsibility for the criminal investigations." "The safety and security of all employees remains KBR's top priority," it said in the statement. "Our commitment in this regard is unwavering."

Over two years later, the Justice Department has brought no criminal charges in the matter. In fact, ABC News could not confirm any federal agency was investigating the case. And it seems that Jones is not the only one. Now members of Congress are calling for formal investigation and hearings into the allegations that also include an environment of sexual harassment and assaults.

Plus: It seems that these days Britney Spears and the paparazzi go hand in hand. Her every move in public, no matter how trivial, gets chronicled by a swarm of videographers and photographers. Their constant presence has even generated some bizarre exchanges. As the video clips and photographs pile up, how much of what we're now seeing is objective reality, and how much is Britney playing the media? As Chris Connelly reports, at last we may be getting some answers. Her latest music video for her new single, "Piece of Me," has turned the tables on those who have besieged her. Connelly's report on Spears also includes never-before-seen footage from the anticipated video for "Piece of Me."

And: When preparing for holiday traditions, despite the anticipation of food, family and fun, many people will also focus on a much more mundane topic: travel arrangements. There are airline reservations to make, hotel rooms to book, perhaps even a cruise to plan. But be careful, because many common assumptions about traveling are nothing but myths. This week, just in time for the holidays, "20/20" examines several different travel myths that could change the way you think about hotel reviews, lost luggage, airplane seating and much more. "Travel: Myths, Lies and Downright Stupidity" includes:

* Ticket buying: When it comes to buying tickets and the internet, are coach fares always cheaper then first class? Bill Ritter reports.

* Lost Luggage: You've heard it before � when it comes to your luggage, the airlines do a lousy job. But the airlines say this is a real myth. True? Jim Avila investigates.

* Lightning: Can lightning take down an airplane? Elizabeth Vargas reports.

* Flight Delays: Who hasn't experienced flight delays? When the airline says your flight is on time, should you believe them? Sam Champion reports.

* Cars and Gas: Even when your cars gas gauge reads "empty," there's still more gas left in the tank. Is that a myth or does empty mean empty? John Stossel reports.

"20/20" is anchored by Elizabeth Vargas and John Stossel. David Sloan is executive producer.
