Secret wedding alert!
There certainly was some foreshadowing for this top secret wedding. Mandy had stated in a previous Us interview that she wanted her wedding to Adams to be "less ... of a big deal." She had said, "Hopefully, it can happen and slip by unnoticed by everybody. I guess we have to be sort of sneaky about it, but I'll see what I can accomplish."
She's a sneaky one, that Mandy Moore. Now if only Speidi could take a page from Ryan & Mandy's modest romance guidebook. (Unlikely.)
