Tiana is getting married today and the theme for her wedding is green! And when I say green, I don't mean money and I don't mean that it will be a nature friendly party - although I'm sure it will be. Nope, it's the color green that will play a big role in the wedding. Tiana, and her bridesmaids Ariel and Elsa, will have the choice of wearing green dresses or green accessories on the big day!
