"What I want to be is honest and someone contestants can look to for guidance as opposed to... the mean one, the nice one. It's not about that," she continued. "I'm me. I am who I am, I'm a producer, I made a lot of records in my life, I know the studio, I live there. I performed all over the world, so it's not about me, me, me it's about them."

And should contestants attempt to belt out a Mariah song?

"They can sing anything that moves them, as a songwriter I would be honored," Mariah said.

As for Nicki - who is known for channeling numerous personas - "Idol" contestants should prepare for something a little crazy if they take a crack at one of her hits.

"I'll probably crack up laughing sometimes because I'm mentally unstable sometimes," the chart-topper said when asked about contestants performing her music. "But they shouldn't be afraid -- it's gonna be fun and pumping!"
