As for Turner, she sported a sleek black jumpsuit, while Goulding dazzled in a black sports coat and matching pants. 

The playlist at the venue included some oldies but goodies, including Lionel Richie's "All Night Long," George Benson's "Give Me The Night," "Another One Bites The Dust" by Queen, "Night Fever" by the Bee Gees, Shalamar's "Night To Remember" and Will Smith's "Men in Black."

Kelce, 34, astonished fans when he joined Swift, also 34, on stage during her "I Can Do It With a Broken Heart" outfit change, adding a memorable moment to her third show at Wembley. Over 80,000 concertgoers watched as Kelce -- wearing a black tuxedo and top hat to match Swift's other dancers -- carried his girlfriend out on stage in his arms. 

There, No. 87 -- who Swift lovingly refers to as "the guy on the Chiefs" when performing "Karma" live -- stood by smiling as dancers stripped Swift of her dress and revealed a white two-piece set underneath.

Before exiting the stage and letting Swift belt out "I Can Do It With a Broken Heart," one of the most-streamed songs of The Tortured Poets Department thus far, Kelce adorably pretended to apply makeup to his lover's face, grinning as Swift pretended to be over the whole situation. 

Fans -- who have adorably bequeathed the couple with the portmanteau "Tayvis" -- quickly took to social media to express their excitement over the impromptu appearance from the NFL tight end, who was spotted earlier in the night in the VIP tent after previously attending the first two shows at Wembley. Swift's first concert on Friday also had his brother, Jason Kelce, and his sister-in-law, Kylie Kelce, in the audience.

"There is something extremely poetic about travis kelce carrying taylor swift away after her heart was shattered....," one person wrote on X (formerly Twitter). 

"Travis Kelce after being in the VIP tent for a third night in a row," another X user wrote, hilariously attaching a clip of Ryan Gosling as Ken in 2023's Barbie.

After the show, one person shared a sweet video of the couple leaving Wembley Stadium with Swift grabbing Kelce's hand while wearing a pink shift dress.

"Travis had a friendship bracelet and a dream less than a year ago, now he's on the Eras Tour stage #LondonTSTheErasTour," one fan wrote, referencing the origins of Swift and Kelce's love story. 

In May, a source told ET that while they are increasingly busy in life, the power couple is very much in love and unafraid to show it. Furthermore, those closest to them would not be surprised should Kelce pop the question and Swift accept his proposal. 

"Taylor and Travis are doing amazing, and their loved ones see an engagement coming sooner than later," said the source. "They make a great match and there's no question about that."

Another source also shared with ET how Kelce and Swift are making their relationship work amid her tour and his imminent return to work when the NFL season begins. 

"Taylor and Travis make sure that the current long-distance aspect of their relationship doesn't last very long. They both move their schedules around if it's feasible and try to carve out as much time as they can to see each other, as well as each other’s families and friends," the source shared.  "They prioritize each other and do anything and everything to make each other happy. Their relationship is genuine and they both want to make it work, so it does."
