Jennifer Hudson
Oscar winner: Jennifer Hudson

Jennifer Hudson has had some significant silver screen success, but it’s still unclear what her musical future will be. She released a self-titled debut album this year and starred as Carrie’s assistant in “Sex and the City: The Movie.” (Kevin Winter / Getty Images)
Fantasia
Broadway babe: Fantasia

Winner of the third season of American Idol, Fantasia Barrino’s first album sold over 2 million copies, but her second album has faltered. No worries! Her autobiography was an instant best seller, and she starred in a Lifetime movie based on the book. She also gained accolades for her Broadway debut as the star in the musical adaptation of “The Color Purple.” (Scott Gries / Getty Images)

Chris Daughtry
Happiest Idol on Earth: Chris Daughtry

The world, the judges and Daughtry himself were shocked when he was kicked off “Idol” before Elliott Yamin, Taylor Hicks and Katharine McPhee. But now Daughtry has sweet revenge. After the show ended, he formed the band Daughtry, and its Grammy nominated debut album was the top-selling of 2007. (Michael Simon / AP)
Taylor Hicks
Angriest Idol on Earth: Taylor Hicks

It took season five winner Taylor Hicks a while to put out his debut album, which finally arrived in stores in December 2006. Hicks has defended the relatively slow sales by saying he is a performer first and his music is best appreciated live, but the silver fox was dropped earlier this month by his label J Records, a label within Sony-BMG. (John David Mercer / AP)
Katharine McPhee
Most Surprising: Katharine McPhee

The gorgeous Katharine McPhee seemed slated for big things post-"Idol.” Great looks, great voice, her signature locks. She had a Top 40 hit with “Over It,” but that didn’t stop her RCA label from dropping her days after fellow “Idol” Hicks was also sent packing. (Scott Gries / Getty Images)

Season 2 of “American Idol” was essentially a two-man competition: nerdy crooner Clay Aiken vs. the Velvet Teddy Bear, Ruben Studdard. Winner Studdard has released three albums and earned one Grammy nomination. (Lawrence K. Ho / LAT)
Clay Aiken
The Squabblers: Clay Aiken

Runner-up Clay Aiken reigned supreme after the conclusion of season two; his first album sold 613,000 copies in one week. Aiken joined the ranks of other “Idol” participants and made his mark on Broadway playing Sir Robin in Mike Nichols’ “Monty Python’s Spamalot.” (Matt Sayles / AP)
