JoJo, 25, began her comeback last year when she released three singles at once, and proved she still has vocal range.
Over the past decade, JoJo released a few other singles after getting out of a harsh legal battle with her old record label, which prevented her from releasing music. She recently opened up with Pop Sugar about how tumultuous that relationship was.
"They wanted me to lose weight fast ... I was injecting myself. This is like a common thing that girls do, by the way. Like, 'the girls,' or whatever. It makes your body only need certain calories, so I ate 500 calories a day. This was the most unhealthy thing I'd ever done," JoJo explained.
This year, the singer is a special guest on tour with Fifth Harmony.
