The Aerosmith frontman and singer/actress Lopez have been linked to the Fox show following the departures of Simon Cowell and Ellen DeGeneres, although the network has yet to confirm or deny the rumours.
Speaking to MTV News, Daughtry said: "It sounds very interesting. I'm a huge Aerosmith fan, so it's going to be interesting to see how his off-stage persona is and how he handles judging the contestants.
"It's also going to be interesting to see if J. Lo can criticise someone, because she's such a sweetheart, but it should be fun. It sounds like it's going to be an interesting year."
Daughtry finished fourth on the fifth season of American Idol, which saw Taylor Hicks crowned the winner.
American Idol returns for its tenth season next year.
