After two seasons, Steven Tyler has decided to leave his judge's seat on "American Idol" to focus on Aerosmith and its upcoming album, "Music From Another Dimension!" In a statement released Thursday (July 12), Tyler announced that, "After some long, hard thoughts, I've decided it's time for me to let go of my mistress 'American Idol' before she boils my rabbit. I strayed from my first love, Aerosmith, and I'm back...The next few years are going to be dedicated to kicking some serious ass." Simon Fuller, "Idol's" creator and executive producer, responded that, "I completely understand his desire to get back to his life as the singer in America's greatest-ever rock band." Fox TV president of alternative entertainment Mike Darnell added that, "We are very sad that Steven has chosen to focus more on his music, but we always knew when we hired a rock 'n' roll legend, he would go back to the music." Fox left the door open for Tyler to return to the show in the future. Tyler's fellow judge Jennifer Lopez has also been coy about whether she'll return to the show or not, while Randy Jackson's contract is also up. Aerosmith is touring North America through mid-August, with a September 22 festival date in Las Vegas. "Music From Another Dimension!" is due out November 6.
