In the Instagram caption, Idina, 43, wrote that she "needed a change," but her change in 'do was not actually related to the Disney film.
Her stylist JT Franchuk told Page Six, "We knew there would be [comparsions to 'Frozen'] …though it's not the reason. Idina has been interested in trying a shade of blonde for a while," he explained. "We started… a few highlights around her face earlier this week…She was loving it, so we took it further."
A week before Idina debuted her new look, Disney officially announced a Frozen sequel. When Idina confirmed to the Telegraph that a sequel and stage show were in the works, she spoke about staying on board for the sequel. "Not the stage show – I don't know what will happen with that – but the movie hopefully. We'll see, she said. "I'm just going along for the ride."
