When you're one of the biggest pop stars in the world marrying one of the NFL's biggest names, it's safe to say the wedding isn't going to be cheap.

But just how expensive was it?

According to The Knot Worldwide, Taylor Swift and Travis Kelce's lavish celebration reportedly carried an estimated price tag of $20 million to $30 million.

That's enough to make even the fanciest wedding planner do a double take.

Turning Madison Square Garden Into a Wedding Venue

One of the biggest expenses?

Transforming the iconic Madison Square Garden into a wedding venue.

The estimated cost to rent the arena, along with several days for setup, teardown, and the massive infrastructure needed to pull it all off, reportedly landed between $5 million and $10 million.

That's before the first guest even walked through the doors.

 Flowers... Lots and Lots of Flowers

If you've ever priced wedding flowers, you know they aren't cheap.

Now imagine decorating one of the world's most famous arenas.

The Knot estimates another $5 million or more went toward floral arrangements, custom décor, elegant draping, carpeting, and transforming the venue into a one-of-a-kind wedding experience.

 Feeding More Than a Thousand Guests

The guest list reportedly included around 1,100 people, and keeping everyone fed wasn't exactly inexpensive.

Catering, staffing, transportation, and event logistics are estimated to have cost between $2.5 million and $3 million.

That's a lot of champagne to pour.

Jason Kelce Stole the Show... Again

Of course, no Kelce family celebration would be complete without Jason Kelce making headlines.

Jason recently described the wedding as "great" and "a good time."

He also joked that he enjoyed well over 15 beers during the celebration.

Honestly... that may be the least surprising wedding statistic of them all.
