It's hardly surprising news considering the huge success of the original movie - but we're still rather excited to report that Disney has confirmed Frozen 2 is in the pipeline.

The first movie became the highest-grossing animated film of all time after its release in 2013, winning two Oscars and the hearts of children everywhere.

And now on the day that short film Frozen Fever hits cinemas Disney has announced that Anna, Elsa, Olaf and Kristoff are coming back for a second full-length movie too.

The studio tweeted: "Forecast: Winter weather ahead! @DisneyAnimation developing #Frozen2."

It also confirmed that directors Chris Buck and Jennifer Lee are returning - despite their recent claim that they knew nothing about the sequel!

Lee tweeted: "At last, I can say - FROZEN 2!!!! I'm beyond excited to create alongside my Frozen family!"

And Kristen Bell - who voices Anna - shared a silly snap of herself resting her head on a bag of ice - describing it as a "rejected" launch photo.

Obviously the cold never bothered her anyway.
