"American Idol" Season 13 premiered on Wednesday with a fresh look and a new panel of judges, which is expected to breathe new life into the show. The famous music competition was a disaster last season with an ugly rivalry cropping up between former judges Mariah Carey and Nicki Minaj.

Jennifer Lopez, Keith Urban and Harry Connick Jr. are the judges for this season. Urban was the only judge from Season 12 to return, while Carey and Minaj refused to come back for another edition.

Not only does the judge’s panel have a new look but the show's producer has been changed as well. According to reports, Per Blankens, producer of “Swedish Idol” has replaced “American Idol” executive producers Nigel Lythgoe and Ken Warwick. And, while Randy Jackson has left the judge's panel, the show will continue to have him on board as a mentor to the contestants.

Connick Jr. tweeted: “seriously - i am most excited about the TALENT this year - y'all are in for one amazing ride... #idoltonight #greattalent.”

Ryan Seacrest, the show's host, tweeted a picture of him with Lopez and Connick Jr. just before the show began, stating: “hold on where’s @keithurban?? We’re starting!!”

To add to the show's revamp, the songs that will be sung by the contestants will also be different from those in previous seasons.

"We have a new approach to the music themes... where the kids can sing songs that they really relate to," Blankens reportedly said. And, all this overhaul seems to have gone down well with the show's fans who have reacted positively on Twitter.

One fan wrote: “So glad @JLo is back on Idol @AmericanIdol.”

Another posted: “I’ll be honest - @AmericanIdol actually looks FUN this season! Can’t wait! #AskIdol.”

A user wrote on Twitter about the judges' interaction with each other: “So excited about this season, loving the judge chemistry more than any previous season!!”
