Steven Tyler on J. Lo: "I'm in Love With That Woman"

Watch out Marc Anthony! Jennifer Lopez has a new man in her life (well, two, actually). The singer/actress will be joining Steven Tyler and Randy Jackson as one of the fresh faces on the American Idol judge's panel, and the Aerosmith frontman couldn't be happier about working with Jenny from the Block.

Steven chatted with Extra after the big Idol reveal yesterday, and quipped that he and J.Lo are having an "outside love affair."

OK! NEWS: AMERICAN IDOL JUDGES FINALLY REVEALED!

"I'm in love with that woman... I think I'm in love with her soul," Steven told Extra.

Jennifer shared some warm sentiments for her fellow judge as well.

"He doesn't know this, but I am a huge fan."

With all the love between the two, is a music collaboration bound to happen?

"In your mind, whenever you think about another artist, you always think about what it would be like to work together," Jen said. "So who knows... we'll see."

Steven stayed mum on any plans of a collaboration, but he does hope to have some solo time on the Idol stage.

"I'm looking forward to grabbing the mic myself some night."

American Idol season 10 begins January 2011 on FOX.
