The first season of Paris Hilton's My New BFF, also known simply as My New BFF and Paris Hilton's American Best Friend Forever internationally, premiered in the United States on September 30, 2008 and is the first incarnation of the My New BFF franchise. 16 women and 2 men competed in challenges in an attempt to become her new best friend. Though Hilton was forbidden from revealing the winner before the show had fully aired, she had on two separate occasions accidentally referred to the winner as a "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, thus inadvertently narrowing down the contestants. On December 2, 2008, it was revealed in the finale that Brittany Flickinger became Paris' BFF.
