Considering the slide of viewership last year, Fox might be banking on it. Albeit "Idol" was the nations favorite program last season (the seventh time it's held that position), it did show signs of weakness. It was beaten in the weekly ratings several times by ABC's "Dancing with the Stars."

A total of 24.2 million viewers watched the ninth season's final duel between Lee DeWyze and Crystal Bowersox, compared to the nearly 29 million viewers who saw Kris Allen claim victory over Adam Lambert last year.

But now with singer-dancer-actress Lopez and Aerosmith frontman Tyler on board, the two could help reinvent the show by offering new musical insight.  They will have the job of trying to match the offbeat chemistry of former judges Simon Cowell and Paula Abdul, which proved to be entertaining in past seasons. While Jackson, the last original member of the "Idol" judging panel, will offer a familiar face viewers might need

In dramatic fashion, Fox announced the new judges via a live press conference Wednesday after months of speculation.

Host Ryan Seacrest first introduced Randy Jackson, who told the crowd of several thousand, "We've found unbelievable talent and I am calling season 10 the remix, baby!"

Seacrest later brought out Tyler, who revealed he wanted to join the show because "it's being a part of something much bigger than yourself. I want to bring some rock to this roller coaster."

Lopez, the last to come out, wore a sparkling silver jumpsuit and got the full diva treatment as she took the stage clouded in special-effects smoke.

"I'm so excited," said Lopez, who is rumored to have scored a $12 million deal to join the show. "I'm looking for the next Michael Jackson."

Tyler and Lopez will both replace Simon Cowell, Ellen DeGeneres, and Kara DioGuardi.

Cowell left the show after seaon 9 in May to work on his next project, "The X Factor," while DeGeneres announced her departure in July, saying that it "it didn't feel like a right fit." And earlier this month, Fox officially confirmed that DioGuardi was also departing, leaving Jackson as the last judge standing on the panel.

For months, fans of the show speculated about who would fill the vacancies.A slew of A-list stars, including Harry Connick Jr., Chris Isaak, Jessica Simpson and Elton John, were rumored to be possible replacements.
