The blockbuster Disney hit "Frozen" turned Idina Menzel into an Oscars performer, being that she was the voice behind "Let It Go." 

According to Billboard, Menzel said on the red carpet during the 2015 Billboard Music Awards, that she couldn't spill too many secrets about the sequel, since it's still at a developmental stage.

"I don't know that much," Menzel said. "Honestly, I think they're in the writing/creative stages, so there's not much to talk about, other than we're really excited that there's a future."

When asked about her part in the upcoming "Frozen" Broadway adaptation of the animated hit, she told the Hollywood Reporter, "I don't know if I feel like hitting that high note eight times a week! ... But we'll see. I would love to be a part of it. It's a great family of people, a great creative team, and you never know."
