Matty Healy's ex-girlfriend Gabriella Brooks saw the lights, the party and the ball gowns at Taylor Swift and Travis Kelce's wedding.

Indeed, the model—who dated The 1975 frontman for four years before Swift’s brief romance with him in 2023—attended the "Love Story" singer's nuptials with her fiancé Liam Hemsworth at Madison Square Garden in New York City July 3, sharing a look inside their enchanting date night.

"The night of our lives," Brooks wrote in a July 5 Instagram post alongside a series of photos showing off her and Hemsworth's wedding looks. "Congratulations T[and]T you are a match made in heaven."

For the occasion, Brooks stunned in a mauve halter-neck gown that featured feathered accents in the lower waist. To accessorize, the 30-year-old paired her look with matching mauve heels. Meanwhile, Hemsworth, 36, donned a simple, yet dapper black tuxedo.

Brooks also gave a closer look at her and The Last Song actor's accessories as she placed a loving hand on Hemsworth's in another sweet shot.

Meanwhile, Brooks also shared a picture of Swift and Kelce's custom-made handkerchiefs, which the couple gifted to their wedding guests.

And in true Swift fashion, they featured a "Blank Space" Easter egg, including the lyrics, "So it's gonna be forever.”

And like Brooks, Healy—who is engaged to fiancée Gabbriette— is on Swift's list of ex-lovers. After all, the Grammy winner dated the "Chocolate" singer for a few months in early 2023 in the wake of her breakup with Joe Alwyn.

While Swift, 36, was on her record-breaking Eras Tour at the time, she didn't let the heartbreak get her down.

“I went through two breakups on the first half of this tour,” the "I Can Do It With a Broken Heart" singer shared in her 2025 Eras Tour: The End of an Era documentary “That’s a lot of breakups, actually. This show is what gave me purpose and what I could use to get me out of bed. The tour has never been the hard thing in my life. The tour has been the thing that allowed me to find purpose outside of the s--t that was going on in my life.

As Swift emphasized, “Men will let you down, the Eras Tour never will.”

In fact, Brooks and Hemsworth were among the many stars who attended Swift's tour. The couple—who have been together since 2019—supported the "Opalite" singer at one of her London concerts in June 2024, watching the epic show alongside Kelce and other celebrities in the VIP tent.

"Taylor we love you!!" Brooks shared in a June 2024 Instagram post, which featured photos and videos from her and Hemsworth's time at the concert. "Best night ever."
