Producers Fox have confirmed judges Jennifer Lopez, Keith Urban and Harry Connick Jr. will take their seats at the panel for the final time in January, with the series set to be a "celebration" of the previous 14.

It hasn't yet been confirmed how long the series - which will again be hosted by Ryan Seacrest - will run, but it is believed to be shorter than in previous years.

Jennifer - who joined the show for two seasons in 2011 before returning last year - recently spoke of how much she enjoys looking for a "new superstar" on the show.

She said: "I love it, it's a great musical journey,. We get to talk about music and we get to hopefully find a new superstar, and that's always exciting."

The show debuted in June 2002 with Simon Cowell, Paula Abdul on the judging panel, with Kelly Clarkson crowned the first-ever winner.

Past judges have also included Nicki Minaj, Ellen DeGeneres, Mariah Carey and Steven Tyler, while other contestants who have gone on to enjoy career success include Jordin Sparks, Carrie Underwood, Jennifer Hudson and Adam Lambert.
