Season 5 runner-up Katharine McPhee also went onto find success following her stint on 'American Idol.'
After coming in second place, McPhee released her self-titled debut album in 2007, which contained the moderately successful singles 'Over It' and 'Love Story.' McPhee would later release the albums 'Unbroken' and 'Christmas Is the Time to Say I Love You' in 2010. McPhee went onto make her big screen debut as Harmony in the film 'The House Bunny,' which starred Anna Faris. McPhee also guest starred on CBS' 'CSI: NY' and NBC's 'Community' before she landed the role of Karen Cartwright on the NBC series 'Smash,' a drama based in the Broadway world.
'Smash' was ultimately canceled after two low-rated seasons in 2013.
