"I Do" by Colbie Calliat- I just heard it for the first time today so I apoligize if it isn't super new
It's a little upbeat so might be good for the entrance to the reception, or cake cutting- super cute though!
Any other new songs on the radio got you thinking about the wedding? I love the one from Glee "Marry You" but the lyrics aren't really the most sincere haha! But perhaps just using the chorus for the entrance would work
