Iggy Azalea and Jennifer Hudson Perform 'Trouble' on 'American Idol'

Following performances at the Kids’ Choice Awards and iHeartRadio Music Awards, Iggy Azalea brought “Trouble” to “American Idol” on Wednesday. But this time Iggy ditched the prison set and kept it simple, performing with just her band and Season 3 “Idol” alum Jennifer Hudson, who was happy to be back.

“It’s been 10 yrs ! My how things have changed ! It’s always an honor to be back!” said JHUD.

In addition to the ladies, Jason Derulo showed off some fancy footwork while performing his newest hit “Want to Want Me,” which has become the most-added track in the history of Top 40 radio. The pop crooner also served as guest mentor to the contestants.
