Camille Kostek has gushed over Taylor Swift's look at her and Travis Kelce's fairytale wedding.

The 34-year-old model told People that the pop megastar "literally was like a real-life princess in her custom Dior" when she married the Kansas City Chiefs tight end, both 36, during their reported $30 million nuptials at Madison Square Garden in New York City on July 3.

Some of the biggest names in entertainment, including legendary singers Sir Paul McCartney, 84, Stevie Nicks, 78, and actor Brad Pitt, 62, were invited to the wedding, in which Taylor and Travis donned custom Christian Dior Haute Couture outfits.

And Camille - who attended with her 37-year-old partner, ex-New England Patriots tight end Rob Gronkowski - was thrilled to see one star among the 1,000 guests.

She said: "[Actress] Julia Roberts - I absolutely was starstruck. Even thinking about her, I lose my train of thought. She's amazing."

Comedian Adam Sandler, 59, was not only invited to Taylor and his friend Travis' wedding, but also officiated the ceremony after he became legally ordained to marry the pair - which guests initially thought was a joke when they saw him standing at the altar.

Recalling the memorable moment on the latest episode of The Compound and Friends podcast, attendee American Century Investments CEO Jonathan Thomas told hosts Sean Russo and Downtown Josh Brown: "Adam Sandler officiated it.

"He came down, everybody laughed and thought it was a joke at first.

"But he probably spoke for 20 or 30 minutes, vacillated between funny, very sincere, sang a few things during his officiating process.

"There are two things that I remember distinctly; one is in your typical vows the officiator says, 'For rich or for poor,' and he said, 'You're not going to have to worry about that.'"

According to Jonathan, Adam told Taylor and Travis to "kiss each other every day, in the morning, at night after dinner, just kiss often".

Jonathan and his Kansas City Chiefs teammates were in tears as Travis delivered his vows to Taylor.

He shared: "Travis went first with his vows. He probably spoke for 30 minutes, and I don't want to violate his privacy, but I was crying, which I was trying to hold back.

"He made himself unbelievably vulnerable. I was sitting there crying, and I was trying to hold it back, until I looked around, and there's all these 300-pound men from the football business crying as well, so I felt really comfortable to let go on it.

"I mean, it was very, very powerful.

"And then Taylor went, and she also wrote her own vows. She probably spoke for 30 minutes, and it was poetic. It was really well done.

"The vows and the ceremony were very solemn, very sincere, very emotional."

Jonathan said the couple's wedding - in which Travis's 38-year-old brother, ex-Philadelphia Eagles center Jason Kelce, served as his best man, while Taylor's 34-year-old brother, music executive Austin Swift, was her man of honour - was an unforgettable experience.

He described: "You would never guess you're in Madison Square Garden the way they did; it was incredible, but you walk through this castle that they built, and behind it, they had all sorts of games, amazing giveaways to people, and then the stage.

"Initially, Taylor and Paul McCartney sang, and then Taylor and Stevie Nicks sang.

"And then for the rest of the night, everybody, the whole entertainment industry - I kept saying if something happens to this building, the entertainment industry in the US is gone - they just popped up on stage and sang songs."

Jonathan added: "At one point, I was dancing with my wife, and without any exaggeration, I had Paul McCartney to my left, Brad Pitt in front of me, Cindy Crawford on [the right].

"We're just surrounded by legends."

He said that Taylor and Travis "went over the top" for the second part of their wedding "to make sure everybody had a great time".
