MTV never aired the pilot and did not pick up the series.Ask Ausiello column, TVGuide.com, May 31, 2006; retrieved July 26, 2006.

In March 2005, McPhee starred as Annie Oakley in a Cabrillo Music Theater production of the musical Annie Get Your Gun.

McPhee had a small role as Paramount Girl in the 2007 musical film Crazy, based on the life of Hank Garland. McPhee filmed the role in early 2005, before she auditioned for American Idol. She has struggled with eating disorders. She told People that at age 13, she began starving herself and exercising compulsively, and at age 17, became bulimic. McPhee gained weight in college due to her bingeing. After seven years of illness, she finally entered a three-month rehabilitation program after successfully passing her American Idol audition; her rehab stint ended just before the Idol semifinals started in February 2006.Sóuter, Ericka; Rizzo, Monica.

Career American Idol

In 2005, McPhee was persuaded by Nick Cokas and her parents to try out for American Idol. She auditioned in San Francisco and sang "God Bless the Child", originally performed by Billie Holiday, and was selected to be a participant in the fifth season, which aired in 2006. After the first round of Hollywood week, she sang "I'll Never Love This Way Again" by Dionne Warwick, which earned favorable comments from the judges. During the second round, she performed in a group, singing "I Can't Help Myself (Sugar Pie Honey Bunch)" by the Four Tops, forgetting the words, but the judges decided to advance the entire group. During the third round, she sang "My Funny Valentine" a cappella and advanced to the top 40. She was angered when fellow group member Crystal Stark did not make the top 24. McPhee's run on American Idol led to the use of the term "McPheever". The inclusion of producer David Foster and singer Andrea Bocelli as guest mentors for Top 6 Week turned out to be a fortuitous introduction for McPhee, as she has worked on various music projects with both men after Idol. In May 2006, McPhee visited her alma mater Notre Dame High School for her hometown celebration.R, Joe. "The Man Who Cried", Television Without Pity at Yahoo.com, May 20, 2006.
