Friend didnt give gift at my wedding- Should I say something?

I got married a few weeks ago. The only guest that didnt give us a gift/card/envelope was from one of my friends whom I've known since I was 10. She also has been married before so she knows the drill about gifts.

After going through all the cards and not finding one from her, I immediately texted her and said that I didnt have her card (only becuase I couldnt beleive she'd come and stiff me). She said that her gift was a surprise. This smells like BS to me. If it was really a surprise wouldnt she have told me at the wedding about it?

SO...do I say something?
