Taylor Swift's boyfriend joins her on stage in Eras Tour

Travis joined Taylor on stage as a dancer for her performance of I Can Do It With A Broken Heart

There are a lot of surprises up Taylor Swift's sleeve as her Eras Tours continues around the UK, but her boyfriend joining her on stage may be one of the biggest ones yet.

American football star Travis Kelce is often seen cheering her on in the crowd, but this time he made an appearance onstage at Wembley Stadium on Sunday 23 June.

Travis appeared dressed in a top hat and tails and carried the singer, who pretended to faint, on to a red piece of furniture.

The US pop star then changed her outfit and performed I Can Do It With A Broken Heart from her latest album, The Tortured Poets Department, to the screaming audience of almost 90,000 Swifties.

What else has happened in London?

Taylor and Travis met Prince William, Prince George and Princess Charlotte

On Friday, the couple met the Prince of Wales and his two eldest children Prince George and Princess Charlotte. Taylor posted the selfie on her social media.

To celebrate her arrival in the capital, murals, a special Tube map, a Taylor trail and a series of events were created.

During the gig, the superstar singer brought out 24-year-old singer-songwriter Gracie Abrams, who sang her new single Us, which features Taylor.

What's next for the Eras Tour?

Dublin in Ireland is the next stop for the tour

The Eras Tour began in the UK with three dates in Edinburgh, followed by shows in Liverpool and Cardiff, before she brought her tour to the capital.

The billion-dollar tour takes fans through different times in Taylor's songwriting and includes hits from albums 1989, Red and Midnights.

The restyled set list, which she first unveiled at the Paris shows, also includes songs from her latest album, released in April.

The tour will now move to Dublin but Swift will return to London to play another five nights at Wembley in August.
