(CNN) -- Fox will reveal Wednesday who will take up the three vacated slots on the judges' panel on "American Idol."
Host Ryan Seacrest confirmed the impending confirmation in a Twitter post last week.
"Looks like I have some new plans on wed!" Seacrest tweeted. "I will be able to introduce the @AmericanIdol judges panel! We will send u a pic! Can't wait"
Fox says the judges will be unveiled in a live webcast at 1 p.m. that can be seen on the show's website. A news conference will follow.
The show begins its 10th season with only one of its original judges, Randy Jackson.
In early September, songwriter Kara DioGuardi stepped down from her role after two seasons on the popular Fox talent contest. The network did not provide a reason for DioGuardi's departure, which came on the heels of comedian Ellen Degeneres' exit from the judging table.
Simon Cowell, known as the show's harshest critic, also abandoned his judging post this year to take up the reins of his new show, "The X Factor."
So, who will be their replacements? Media speculation has focused on singers Jennifer Lopez and Steven Tyler.
