Keith Urban will return as an American Idol judge, but the other judges have still not been determined. Urban's continued involvement in the show was announced Thursday (Aug. 1) during a press event in Los Angeles. Urban later confirmed the news by tweeting, "Thrilled to be back on @AmericanIdol with my pal @RyanSeacrest and dying to know who the other judges will be!" Former Idol judges Mariah Carey, Randy Jackson and Nicki Minaj will not be returning for the new season. Their replacements are expected to be announced within the next few weeks.
