"American Idol" is betting that a judges panel remix with Jennifer Lopez, harry Connick Jr. and Keith Urban will work better with viewers than bickering divas Mariah Carey and Nicki Minaj did last year.   

Today, Fox announced the addition of Lopez and Connick as judges for season 13.

Jennifer Lopez will be back on "Idol" after a two-season run as judge in 2011 and 2012.  Harry Connick Jr. is a respected jazz singer and musician who has been a mentor on 'Idol' several times.

Keith Urban's return to the show was announced last month by Fox Chairman Kevin Reilly, who said the country star didn't get a chance to show his personality in his first season as a judge.   Urban appeared overwhelmed last season by the Carey-Minaj crossfire that drew complaints from many viewers.

Fox has also announced that original judge Randy Jackson, who left the show, will be back in anew role as in-house mentor to the contestants.  Ryan Seacrest will host again.  He has been with the show since season 1 in 2002.
