The guests are talking, even if the couple isn't. Three days after Taylor Swift married Travis Kelce at Madison Square Garden in New York, the people who were in the room have started posting about it, one calling it "an unbelievably brilliant night", another confessing to "the world's greatest hangover", while Swift and Kelce have released no photos and no statement beyond the initial confirmation.

The pair, both 36, wed on Friday 3 July in a ceremony officiated by comedian Adam Sandler, a representative for Swift confirmed to ABC News in the United States. Around 1,000 guests attended across a two-day celebration. Bride and groom both wore custom Christian Dior haute couture by the house's creative director Jonathan Anderson.

There was no bridal party. Swift's brother Austin was "man of honour" and Jason Kelce was his brother's best man. Guests told Yahoo Entertainment the vows were self-written and ran about 20 minutes each, with Swift singing parts of hers, and that Paul McCartney and Stevie Nicks both performed at the reception.

BBC Radio 1's Greg James was among the first to post. "True to her word, of course the invitation arrived and of course I couldn't tell anyone. And oh my god, what an unbelievably brilliant night," he wrote on Instagram, adding later that he was "currently experiencing the world's greatest hangover". Jessica Alba congratulated "T&T" on "such a beautiful night", and the groom's mother Donna Kelce offered the shortest review: "I really can't say a heck of a lot but it was magical, man, magical."

The scarcity is by design. Guests were under a strict no-phone policy and instructed not to share details or images, and as of Monday no official photographs had been released. AMC Theatres chief executive Adam Aron posted that the night "felt intimate and small" despite the numbers, then deleted the post. Outside, fans packed behind police barricades in 38-degree heat, with 31st Street closed from Thursday evening.

Before the wedding, the couple donated US$26 million to around 20 charities, a figure announced through Swift's representatives and reported by Variety and CBS News. The recipients included US$2 million to Dolly Parton's Imagination Library and US$1 million to New York food charity City Harvest.

What happens next is the part the industry is watching: no wedding photographs have been sold, given away or leaked, which for an event of this scale is close to unheard of. Until the couple decides otherwise, the public record of a wedding this size is a handful of morning-after Instagram posts, and they are keeping it vague.
