During a Facebook Live chat backstage at the American Idol finale rehearsal on April 4, Jennifer Lopez answered some standard fan questions about the show — what do you love the most about being a judge? What are you going to wear on the last episode?

Things took an exciting turn, however, when one fan asked for a preview of the fiery new song, "Ain't Your Mama," she plans to debut during her performance on the last-ever American Idol. And she actually played a snippet. Expect lyrics like, "I ain't gonna do your laundry, I ain't your mama," and press play above to hear the catchy tune for yourself (around the 1-minute mark). Then, remember J Lo's hottest Idol outfit ever.
