[artist id="508574"]Jennifer Lopez[/artist] feels really at home as one of the [article id="1656656"]new faces of "American Idol."[/article] But Lopez isn't the only new kid on the "Idol" block: Aerosmith frontman [artist id="1204674"]Steven Tyler[/artist] is also just getting his feet wet, and fans are getting used to his wacky judging style. And J.Lo appreciates her fellow judge's "zaniness," as she called it.

"He's a very spontaneous person in that sense," she told MTV News. "You never know what's going to come out of his mouth, [and] probably half the show is me kind of looking at him like, 'What? Did he just say what I think he just said?' It's very funny, but I enjoy every second of it -- every second of the zaniness and craziness. You never know with him, and it's awesome."

Lopez said "Idol" executive producer Nigel Lythgoe approached her and Tyler about hitting the stage together during one of the live shows, and she's considering the idea.

"He was like, 'You know, I'd love for you to perform,' " she recalled. "And I was like, 'We'll see. You know the single [[article id="1656553"]"On the Floor"[/article]] is actually coming out soon.' And he was like, 'I'd love for you to perform with Steven.'

"It could be so fun," she continued. "And Steven and I have a real love for each other. We really respect each other, [but it has to be] the right song, the right moment. It could be good."
