If you've seen her interview - in A Very Gaga Thanksgiving video - You'll see she says : " No matter how many choppers are flying over head - I'll make sure they don't get even 1 picture becoz marriage for me is very private & a sacred thing " ..
I think the video will involve something with a bride. Remember the behind the scenes picture for when she was filming. She had a veil and her dancers were it suits. It's a possibility.
