Idina Menzel Dyes Her Hair Blond, Looks Like Elsa From 'Frozen'

— -- Idina Menzel just made a lot of "Frozen" fans very happy.

The actress, who voiced Princess Elsa in the Disney film, has dyed her hair blond, calling to mind her royal character.

"Look what me and my girl @jenytamera did today. Needed a change. Loving it! #brunettetoblonde #blondehairdontcare," Menzel wrote on Twitter.

Menzel, 43, has had a busy 2015, and it only seems to be getting busier. Last month, she sang the national anthem at the Super Bowl and presented an Oscar alongside John Travolta. And just a few weeks ago, Disney announced plans for "Frozen 2." She's also writing new music, she announced on Twitter.

"Getting excited. About this summer. Maybe I'll play some new songs? #seeyouthissummer #worldtour," she wrote.
