First season Sixteen women and two men competed in challenges in an attempt to become Hilton's new best friend. Four of the female contestants were eliminated in the first episode and hence did not feature in promotional material (photo shoots, television spots or even the opening credits) for the season. Guest stars included
Benji Madden,
Kyle Richards,
Richie Rich,
Traver Rains,
Kathy Hilton,
Fergie,
Simple Plan,
Chris Applebaum,
Perez Hilton,
Dirt Nasty,
Allison Melnick,
Ryan Seacrest,
Nicky Hilton,
Keyshia Cole,
Jeff Beacher and
Nick Swardson. Though Hilton was forbidden from revealing the winner before the season finale aired, she had on two separate occasions accidentally referred to the winner as "she" —first on the September 25, 2008 airing of the
Late Show with David Letterman, and again on the October 7, 2008 airing of
The Ellen DeGeneres Show. On December 2, 2008, it was revealed that Brittany Flickinger had won the contest. In the episode "Vegas, Baby!", Paris takes the girls to compete in the
Folies Bergere at The Tropicana Hotel Las Vegas.
Second season Thirteen women and three men competed in challenges in an attempt to become Paris's latest best friend "forever." Hilton said that she did not stay friends with the first season's winner Brittany Flickinger because "I loved her and I trusted her, but sometimes people get too caught up and they change". Previous contestant Nelson "Onch" Chung appeared as a co-host, while Natalie Reid (a professional Paris Hilton-lookalike who also appeared with Hilton in
The Simple Life), made a special guest appearance as Hilton's double in the first episode. Other guest stars included
Santino Rice, Kathy Hilton,
Doug Reinhardt, Allison Melnick,
Lil' Kim,
Three Six Mafia, and
Kathy Griffin. This is the first and so far only format of the series to include
straight men in the competition. David and Chris were added to the competition in episode four, and they do not appear in promotional material for the season. On August 4, 2009, it was revealed in the finale that the contestant Stephen Hampton had won the competition. ==Broadcast history==
