Jennifer Lopez will return to American Idol as a judge next year.

The singer, who appeared on the show in 2011 and 2012 before leaving and returning a year later, will line-up alongside Harry Connick Jr. and Keith Urban once more.

Ryan Seacrest will continue to host the popular US TV talent show.

21st Century Fox senior exec vp David Hill commented: "Jennifer, Keith, Harry and Ryan are the very best in the business at what they do, and I’m thrilled that they are returning to American Idol for another season.

"Each brings unique qualities and expertise to the team, but they all share the same passion for helping undiscovered singers achieve the American dream."

Last year's American Idol meanwhile was won by Caleb Johnson.
