Travis Kelce shocked fans as he joined Taylor Swift onstage at a sold-out Wembley this evening – in front of the likes of Fleabag’s Andrew Scott and Sir Paul McCartney.

It is the first time the pair have taken to the stage together, after officially announcing their relationship on Instagram on Friday evening.

Tonight the American footballer joined Taylor onstage for a costume change before the song I Can Do It With a Broken Heart – sending fans into a frenzy once again.

The athlete was dressed up in a white bow tie, tailcoat and top hat.

He picked Taylor up before fanning her and powdering her face as part of the act.

Before Taylor carried on with her performance, she made sure to blow a kiss to her NFL beau.

The couple, who have been romantically linked since 2023, have never featured on each other’s social media accounts.

But Taylor ‘hard-launched’ their relationship by posting an adorable photo of herself and Travis posing with the Prince of Wales and his two children – Prince George and Princess Charlotte – which fans branded ‘iconic’.

The 34-year-old singer has been dropping hints about her relationship with the NFL player for a while now.

During her sell-out Eras Tour, Swift changed a lyric in her popular song Karma from ‘Karma is the guy on the screen’ to ‘Karma is the guy on the Chiefs’ – referencing Travis’s Super Bowl winning team.

Eagle-eyed Swifties have also spotted Travis in the VIP tent making loving gestures at Swift throughout her three-hour long set.

But tonight Swift had eyes for her crowd as well as her new boyfriend.

Adoring fans stood, cheered and stamped their feet for over five minutes – leaving the megastar speechless.

Tonight rock legend Jon Bon Jovi joined the 89,000-strong crowd alongside Sir Paul McCartney, Ellie Goulding and Cate Blanchett.

Fleabag’s own Phoebe Waller-Bridge was also spotted in the VIP tent dancing to Love Story with Andrew Scott.

Her set-list lasts for three hours and consists of songs from all of her albums

Eras Tour tickets have been going for hundreds of pounds a pop, with many fans eager to catch a glimpse of the US singing sensation before her tour moves onto Ireland next week.

But she will be back soon enough, with the 34-year-old set to play five more dates at Wembley in mid-August.

Supporters of the chart-topping star, who is on an epic worldwide tour following the release of her album Midnights last year and The Tortured Poets Department this year, were convinced that the superstar was going to make a huge announcement during her third night at Wembley Stadium tonight.

Some guessed she was going to announce the re-recording of her album Reputation – referred to as Rep TV (Taylor’s Version).

Her recent shows have seen complaints of glitching happening on the screen behind her as she performs.

But fans suspected that this was a build-up to the announcement, when they anticipate the screen will glitch and go completely black.

Despite the theories, the only surprises at tonight’s concert were Travis’s appearance and the acoustic songs she played – which are different every night.

Fans screamed as the 34-year-old sang an unexpected mash-up of Out of the Woods, Is It Over Now and Clean.

Over the last couple of days it seems everyone who is anyone has been seen at her London shows.

The first two nights on Friday and Saturday brought out some of the biggest names in Britain, with Prince William and his children Prince George and Princess Charlotte making an appearance.

The Prince of Wales was filmed eagerly joining in with the crowd – which also included fellow royals Zara and Mike Tindall.

Yesterday Tom Cruise was spotted trading friendship bracelets with Swifties, while Hugh Grant treated himself to a mid-concert snack of carrots.

And tonight Sir Paul McCartney danced with fans at tonight’s show as Jon Bon Jovi, Phoebe Waller Bridge and Andrew Scott kept themselves hidden in the VIP tent throughout the performance.
