The event has begun but some fans still haven’t given up hope that they’ll get a glimpse of their favourite artists. People of all ages adorned in their Taylor Swift memorabilia are lingering around Madison Square Garden, climbing city scaffolding, and cheering for anyone who walks past - including emergency responders, who looked thoroughly entertained by the crowd.
This event feels like a Hollywood who's who similar to the Met Gala - which takes place just uptown from here - except this time, the celebrities haven't stopped to smile for the cameras. Though the crowd of spectators is dwindling, the true fans are sticking around.
The celebration begins - but no sign of the wedding party

The SUVs have stopped rolling, the curtains have been drawn back and Taylor and Travis's big night is beginning.
We're still not 100% certain what the ceremony will entail and US media reports suggest the couple may have tied the knot in advance of today's celebration.
Whatever today is, they have shut down huge swathes of one of America's biggest cities for it, and even the Empire State Building will be lit up to mark the occasion.
Meanwhile, Madison Square Garden is so dense with stars it threatens to collapse into a black hole.
We've spotted Bradley Cooper, Mariska Hargitay, Karlie Kloss, Ed Sheeran, Gigi Hadid, Hugh Grant, Graham Norton, Camila Cabello, Ethan Hawke (who apparently took an Uber), Jason Sudeikis and almost all of the Kansas City Chiefs turning up in the last few hours.
Swift's childhood best friend Abigail Anderson Berard, meanwhile, was spotted leaving her hotel in a floral corset - potentially revealing the design of the bridesmaids' outfit.
What we haven't seen is anyone who might be presumed to be part of the wedding party, from Selena Gomez (who will be returning the favour after Swift acted as bridesmaid at her wedding to Benny Blanco last year), to Travis Kelce's brother Jason. It's thought they entered Madison Square Garden much earlier in the day.
In total, we're expecting around 1,000 guests inside the venue - with rumours that Stevie Nicks and Paul McCartney will seranade the happy new couple.
But with strict privacy protocols in place, we won't know any more until they choose to share it with us.
Fans thrilled to be in New York for the wedding buzz

On the streets around Madison Square Garden, some young women have been breaking into Taylor Swift songs - standing atop a scaffolding and taking photos of the cars going in.
“It’s a moment when even if you don’t care about Travis and Taylor, you have to be here," says Alexandra Dinomite, who thinks Swift is the closest the US has to royalty.
“God bless Taylor Swift and may they be very happily married. She closed the whole city!” says Mariana Nascente who is originally from Brazil but now lives in New York City.
Fellow Brazilian Jamile Lanjoni says she is so excited to live in this city right now because a lot of things are happening, including the World Cup.
Is Radio 1's Greg James in New York?

Taylor Swift invited BBC Radio 1's Greg James to her wedding live on his radio show last October. My colleagues at the station have been busily checking his holiday schedule ever since...
But doubts were raised he could attend the bash this weekend, because he was due to take part in the Crossed Wires podcast festival in Sheffield.
He was there last night, on stage with his friend Alice Levine. On Radio 1 this morning, she confirmed he'd gone out drinking afterwards. But this morning? No-one could get hold of him.
He wasn't on air for his breakfast show. And when stand-in hosts Sam and Danni tried to phone him, his voicemail had been changed to a Taylor Swift song.
And then, just 25 minutes ago, he posted a photo to his Instagram story of a woman in a gown and a man wearing formal shoes.
The plot, as they say, is thickening like a stodgy custard.
Taylor Swift's Toy Story 5 hit in top 10 in UK and US
Taylor Swift may be busy with wedding preparations, but she still has time to make it into the top singles charts.
Her new song "I Knew It, I Knew You" is currently charting in the UK top 10 of the Official Singles' Chart, after it was released it early last month for the movie Toy Story 5.
It is currently seventh on the chart, behind hits from Olivia Dean and Sam Fender, and Olivia Rodrigo among others.
Across the Atlantic, the song is at number two on the Billboard Hot 100, behind Ella Langley's "Choosin' Texas"
Traffic at standstill near Madison Square Garden

US reporter in Manhattan - Favourite song: The Way I Loved You
Midtown Manhattan is extremely chaotic even on an average Friday. It’s home to offices, tourist attractions like the Empire State Building, and the city’s busiest transit hub, Penn Station.
But today, with the holiday weekend and a celebrity wedding coinciding, the area around Madison Square Garden is at an absolute traffic standstill.
Pedestrians and drivers are stuck behind dozens of black SUVs with tinted windows, presumably carrying some of the most famous faces in entertainment on their way to the rumoured Swift-Kelce wedding at MSG.
I was stuck behind all of the black cars for about 20 minutes before I decided to jump out of my Uber and walk the remaining few blocks to the venue.
The celebs in their formalwear probably don’t have that choice. I hope they’re not late to the function!
Wedding guests arrive ahead of star-studded celebrations
A group of four people - two men dressed in black tie and two women dressed in evening dresses - have just been seen walking through a security gate at Madison Square Garden.
They hold their phones up to a member of security at the gate who has a look at the screen before typing on a tablet, and they disappear behind a cordoned off area.
Moments later another couple, including a woman in a silver dress, arrive at the same gate and also have their phones checked.
Meanwhile, a queue of three black 4x4s can be seen travelling through a black curtain into a secluded area.
