In the end, Taylor Swift and Travis Kelce’s marriage was announced to the world like something out of one of her music videos: Billboards outside of Madison Square Garden lit up in purple with the message “JUST&T MARRIED” announcing the news to those on the streets of Midtown Manhattan and the entire globe.

A few blocks over, the Empire State Building was lit up in blue in their honor, a nod to the age-old wedding rhyme. Then, a rainstorm began.

The milestone marks a new era for the couple, whose romance played out in the public eye, until they threw a wedding shrouded in secrecy thanks to what were said to be ironclad non-disclosure agreements and TSA-level security.

Leading up to the big day, which began Thursday evening with what was described as a rehearsal event for about 100 attendees, few guests would even confirm they were invited and even fewer confirmed they would be attending.

Watching the arrivals at Madison Square Garden, where Swift has performed eight times in her 20-year career, wasn’t just like any celebrity-packed red carpet. It was like watching the arrivals at the Grammys, Oscars and ESPY Awards combined. Everyone from Ed Sheeran to NFL Commissioner Roger Goodell was spotted, as were several Kansas City Chiefs players, many of whom were captured loading into blacked-out Sprinter vans from a swanky hotel that media and some fans staked out.

Social media was flooded with images and footage of guests making the pilgrimage to MSG. “Law & Order: SVU” star Mariska Hargitay, whose character inspired one of Swift’s cat’s names, lowered her window and greeted onlookers.

It all took place amid a sweltering, scalding heatwave that saw temperatures reach triple digits, tough scene for those outside without an invite.

So – what really happened inside MSG last night?

Instead of opting for a traditional bridal party, Swift’s brother Austin served as her “man of honor” and Kelce’s brother Jason acted as his “best man,” according to an emailed statement from Swift’s representative, issued in tandem with the billboard messages.

The bride and groom both wore custom Christian Dior looks designed by Jonathan Anderson, who’s known for elaborate, mischievous designs.

The couple’s friend Adam Sandler, who gave Kelce a cameo in “Happy Gilmore 2” last year, served as their officiant.

“The ceremony was great, moving. Adam Sandler, funny and touching. Vows, everything you would hope for – real, vulnerable, serious and silly, deeply loving,” “Good Morning America” anchor George Stephanopoulos, who attended the wedding alongside his co-anchors Robin Roberts and Michael Strahan, told ABC News after the wedding.

Roberts and Stephanopoulos said the couple wrote their own vows in “little books.”

A photo shared to personal trainer Rob Jordan and his wife Joann’s Instagram accounts Saturday offered a first glimpse inside the wedding that Stephanopoulos described as “a garden inside the Garden.” The couple held hands as they walked up an orangey carpeted staircase to what appears to be the entrance to the wedding. Joann Jordan told CNN their phones were taken when they reached the top of the staircase for check-in.

The apparent orange color was the subject of a massive marketing campaign and fan theories surrounding Swift’s 12th studio album, “The Life of a Showgirl,” released in October. “It feels like kind of energetically how my life has felt,” she said about the album’s orange iconography.

Stevie Nicks was among the performers of the evening, Roberts confirmed. Page Six was the first to report Nicks’ expected performance. Asked about the performances, Jay Marciano, CEO of live event company AEG Presents, told Reuters there were “big ones.” The highlight? “Too many. All of them,” he said.

What did guests take home? Two Instagram posts from singer-songwriter Maren Morris and Ana Demmer, who is newly engaged to Kansas City Chiefs center Creed Humphrey, show what could be a favor from the celebration: a handkerchief embroidered with “T&T,” the date and “New York City,” along with the “Blank Space” lyric, “So it’s gonna be forever …”
