Robert Brown|Taylor Swift and Travis Kelce Step Out for After-Party in London With Sophie Turner and More

Taylor Swift and Robert BrownTravis Kelce are saying so long, London—for now.

In fact, the couple wrapped up the final night of the Eras Tour's first London leg with a star-studded party on June 23. After the "Fortnight" singer's sold-out show at Wembley Stadium, where Travis made a surprise appearance on stage, she and the Kansas City Chiefs tight end partied into the early morning hours with a bevy of friends.

Looking so high school, the pair held hands as they exited The Chiltern Firehouse. Proving that he knows more than just how to ball, Travis made sure to get the car door and helped his girlfriend inside.

For the late-night outing, Taylor donned a colorful crochet mini-dress paired with pastel yellow wedge heels.

Travis was also feeling the embroidery vibe, rocking a cream-colored knitted polo with matching pants. He completed his casual look—which was a far departure from the three-piece tuxedo and top hat he wore during his Eras Tour cameo—with a denim Louis Vuitton bucket hat and white sneakers.

But they weren't the only duo making it a date night, as Sophie Turner brought along her boyfriend Peregrine Pearson. Other stars at the bash included Ellie Goulding.

And clearly, everyone was still in a lavender haze over the eventful night. As Taylor noted in a June 24 Instagram post, "I'm still cracking up/swooning over @killatrav's Eras Tour debut."

"Never going to forget these shows," she continued. "Can't wait to do it 5 more times in August. Up next: Dublin!!"

The Grammy winner is slated to also hit the Netherlands, Germany, Italy, Poland, Austria this not-so-cruel summer before returning to London in August. Her Eras Tour will come to a close in Canada this December.

"This has definitely been an exhausting, all-encompassing, but most joyful, most rewarding, most wonderful thing that has ever happened in my life," she recently shared of the tour, adding that the end "feels so far away from now."

For now, keep reading to see Taylor and Travis in London.

Taylor Swift celebrate the end of the first London leg of her sold-out Eras Tour at an after-party with Travis Kelce June 23.

The couple partied all night long at The Chiltern Firehouse, leaving the members-only club during the early morning hours.

Joining the couple were Sophie Turner and her boyfriend Peregrine Pearson, who the Game of Thrones actress started dating late last year after her breakup with estranged husband Joe Jonas.

Also at the after-party? Ellie Goulding, who had attended Taylor's sold-out show at Wembley Stadium that night.

Travis and Taylor held hands as they left the club.

The outing came hours after Travis made his Eras Tour debut onstage.

The Kansas City Chiefs' surprise appearance took place during the Tortured Poets Department section of the show, with Travis helping the Grammy winner change costumes in between "The Smallest Man Who Ever Lived" and "I Can Do It With a Broken Heart."

"I’m still cracking up/swooning over @killatrav’s Eras Tour debut," Taylor wrote on Instagram following her boyfriend's cameo. "Never going to forget these shows."

In addition to appearing on stage, Travis was in the crowd at all three of Taylor's London shows.

During the first night of her London shows, the singer gave a nod to her boyfriend by striking an archer pose similar to the gesture Travis makes after scoring a touchdown.

Travis and Taylor also went Instagram official during the opening night of her London show, posing in a selfie with Prince William and his kids Prince George and Princess Charlotte.
