Here's what we know so far...

Swifties have been waiting to find out the details of Taylor Swift's upcoming wedding; despite guests having to sign NDAs, it seems some of the details have been leaked...

We already know that Madison Square Garden is the venue and that it will be closed for 3 days for the wedding.

The nightly cost of the prestigious venue is approximately $2 million, which sounds like a lot; however, it is rumoured that the wedding budget is $20 million.

Taylor Swift is having 6 different wedding dresses prepared, but will only wear one. The other 5 wedding dresses were ordered to surprise the paparazzi. The cost of the wedding dresses is $1 million.

4 hotels in Manhattan will be closed to guests. Hotel room nightly rates range from $1,500 to $3,000. Therefore, the accommodation bill will exceed $2 million.

The security operation will cost approximately $5 million, and it is rumoured that the FBI will be the security for the event.

Special performances in a mini-festival atmosphere are expected at the wedding at this time; no specific artists have been confirmed. 

These details are, of course, all rumours; whether we will even find out if they're true after the event, we don't know, as we said, all the guests had to sign NDAs.
