"I Do" is a song from Cinderella III: A Twist in Time. It is a solo sung by Anastasia, expressing how she finally gets to be with Prince Charming, believing she has finally found someone who truly loves her and all her wishes will come true.
Now there is finally someone to love me.
He'll show me a world that I never knew.
With two simple words.
All my dreams will come true.
I do, I do.
