Taylor Swift and Travis Kelce's wedding guests lift the lid on couple's 'long and irreverent' vows

and Travis Kelce - and it didn't take long for guests to start spilling what happened behind the velvet curtain, including intimate details of the couple's vows.

After months of feverish speculation, cryptic clues and endless wedding rumors, the superstar couple tied the knot in front of around 1,000 family members, friends and A-list celebrities during an on Friday.

The blockbuster event was packed with headline-making moments, from officiating the ceremony to Swift's brother Austin standing by her side as her 'best man' instead of a maid of honor.

Then came another surprise when Sir took to the stage during the reception to perform I Want to Hold Your Hand, leaving guests stunned.

But while the celebrity cameos grabbed headlines, fans were far more eager to know what the newlyweds said at the altar - especially with songwriting icon Swift penning her own vows. 

Just hours after the lavish celebration wrapped, one wedding guest lifted the lid on the ceremony itself, describing the couple's vows as 'long, entertaining, personal, charming, emotional, irreverent and endearing' in a remarkably detailed post on X.

The guest was AMC CEO Adam Aron, who shared an unusually detailed account of the ceremony in a since-deleted post.

'Then the vows. Long, entertaining, personal, charming, emotional, irreverent and endearing explorations by each as to how they met, why they want to be with each other for all eternity, the promises they made in joining their much-beloved two whole families (Kelce's and Swift's) as one, and committing to their new mutual life together,' he wrote.

Aron said the ceremony took place inside a transformed Madison Square Garden that 'did not look like Madison Square Garden,' with the venue draped in 'peach and white' and decorated with oversized photos of the bride and groom from childhood through their teenage years.

According to Aron, Kelce looked 'handsome' in a white tuxedo while Swift stunned in a white wedding gown with a long veiled train before an officiant who was 'warm and welcoming, funny and eloquent' led the ceremony.

After the couple sealed their marriage with what Aron described as a 'sweep you off your feet kiss,' guests moved into an elaborate 'Secret Garden'-themed reception featuring five-story illuminated trees, an A-list crowd, lavish food and drink and plenty of music.

He ended his post by calling the ceremony 'real, pure, true joy' and declaring that, in a world filled with conflict and division, the couple's wedding proved 'that love conquers all.'

Aron wasn't the only wedding guest to offer a glimpse inside the ultra-private ceremony.

During Saturday's Good Morning America, hosts Robin Roberts, Michael Strahan and George Stephanopoulos revealed they had all attended the star-studded celebration and echoed Aron's description of an event that somehow felt intimate despite taking place inside Madison Square Garden.

As the trio reflected on what Roberts called the couple's 'dream wedding,' conversation soon turned to the ceremony itself and the vows that had captivated fans.

'Oh, and their vows,' Roberts said, sounding visibly impressed. 'They wrote their own. Mmm.'

While Roberts didn't divulge any further details, her comments appeared to reinforce Aron's account that the personal exchange between Swift and Kelce was one of the standout moments of the day.
