She's already sent a handful of singers through to Hollywood Week on American Idol, but newbie judge Jennifer Lopez admits that some of the best female vocals she's heard can be found at her very own home.

"It's funny when you listen to her, because...she sings out of pure joy and pleasure," Lopez, 41, tells Rachael Ray of her 2-year-old daughter, Emme.

But the tyke isn't ready to belt out tunes for an audience just yet.

"The minute she thinks you're watching her, she stops," the proud mom tells Ray during an appearance to air Monday on The Rachael Ray Show. "But she has a beautiful little voice, almost like a little Shirley Temple vibrato type thing."

As for Emme's twin brother, Max, Lopez says he's happy to be the center of attention.

"We travel a lot, and the minute we get anywhere, we put everything away," Lopez tells Ray. "No flowers, no nothing, no cups, no forks, no knives, no fruit. [He's] into everything, and just wants to throw and break everything in the world."

Married to Marc Anthony since 2004, the singer-actress has said she can't wait to give Max and Emme a little brother or sister.

"As soon as I had the babies, I thought to myself, 'I want to [get pregnant] a thousand more times,'" Lopez has said. "I love this. This is life."
