This little girl stole the show from the bride, and I think the bride is okay with it!

Six-year-old Emma had been walking around the house, singing "Love Is An Open Door" from the movie "Frozen" with her mom. So when she and her mom were asked to stand up in a wedding, Emma thought this would be a great opportunity to serenade the new couple.

Her mom, Mel, said that it was "100% her idea." Looks like her great idea paid off! The look on the bride's face is priceless. Nicely done, ladies!
