In this episode Alex mentions to Walker that twins run in her family. There was a joke about this on-set because twins really do run in Chuck Norris' family.
Alex: I can't believe we finally made it to Paris.
Walker: You said on the plane that the second thing you want to do when we get to Paris was go for a walk. What was the first thing you wanted to do?
(They close the hotel window)
Alex: Oh, Walker, we may never take that walk.
Tracy Lawrence sings Stars over Texas during the wedding, Just You and Me during the bride/groom dance and Long Wet Kiss when the wedding party all dance.
While filming the part of the wedding when Stars Over Texas was playing, Sheree J. Wilson said in an interview that she started crying and the prop master came over and said 'Guess what Sheree, this ain't real.'
When the song Long Wet Kiss plays we see Walker dancing with 2 little girls and Alex dancing with a little boy. The 2 little girls are Chuck Norris' granddaughters and the little boy is Sheree J. Wilson's son.
