Before Mandy Moore was a brunette actress, she was a blonde singer. Now that This Is Us is on hiatus and she is a new mom, she decided to go back to her roots.

No matter what color her hair is, she is always beautiful.

And for you fans of Rebecca Pearson, she will go back to brown when they go back to work on the final season of the NBC drama.
