Voice coach Melissa Black is calling the youngest “American Idol” in history a liar. Mel claims that “Idol” winner Jordin Sparks lied when she said she never had any formal vocal training.

“Jordin was just 14 years old when she studied with me in 2004,” vocal coach Melissa Black tells Star magazine. “Her mom, Jodi Sparks, and her grandmother, Pam Wiedmann — who acts as her manager — found me on the Internet. We were together for nine months of intense vocal work, with Jordin taking one 30-minute class a week…”

Black says they haven’t spoken since Sparks stopped taking the classes, and she said mostly good things about her alleged former student. Nevertheless, Black admits, she was “hurt for a week” when the “Idol” winner said that she hadn’t had any formal training. “Jordin didn’t have to mention my name, but at least acknowledge you had training,” she told the tab. “But I’ve moved on, and I hold my head up high.”
