But her baby gave her purpose and meaning helping to fill the wholes left by a failed relationship. It was one of the most emotional moments ever on Idol and provided a strong message to young single moms every. It’s not your fault. It’s not a mistake. You have a purpose in life and that’s to raise the little angel you’ve been blessed with. Watch the performance here.
