With the blockbuster success of Frozen turning Idina Menzel from a much-loved Broadway vet to a Tony-winning household name, the voice behind "Let It Go" is inevitably going to field a few questions about the Disney film's recently announced sequel. On the red carpet of the 2015 Billboard Music Awards, Menzel said 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," said Menzel. "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."
