It's been the worst kept secret in Hollywood, but now American Idol has made the official announcement:

Jennifer Lopez and Steven Tyler will join Randy Jackson as the new season 10 judges. The artists were introduced at a press conference today, with Lopez making like Paula Abdul and telling an audience that included many aspiring contestants:

"I love you guys. I am so excited. It is about concentrating in the moment, do the best you can. Just live! Just live, it's your moment."

J. Lo also set the bar impossible high for next year's finalists, saying: "I'm looking for the next Michael Jackson."

Tyler, meanwhile, was referred to as a "rock legend" by Fox executives and summed up his inclusion on the show with:

"[It] feels like the perfect feathered nest. It's being a part of something much bigger than yourself. I want to bring some rock to this roller coaster."
