While not an official announcement, the first news about a sequel to Frozen -- the highest-grossing animated film to date -- was revealed this weekend, when the actress behind one of the main characters confirmed that Disney has plans for a follow-up.

Idina Menzel -- who voiced the magical ice princess Elsa, and sang the film's hit song "Let It Go" -- was profiled by The Telegraph this weekend, and when asked about a sequel, as well as a live musical show, she said that they're both in the works. However, when asked if she was signed up for either, Menzel replied: "Not the stage show – I don’t know what will happen with that – but the movie hopefully. We’ll see. I’m just going along for the ride.”

While it's not exactly a surprise that Disney would want to further cash-in on their biggest animated film, it's unknown whether the sequel would be a theatrical release or direct-to-video.

Frozen is the highest-grossing animated film of all time, earning over $400 million domestically and $873 million at the foreign box office. Characters from the animated film have also made live-action appearances on ABC's Once Upon A Time.
