Taylor Swift 'swooning' over Travis Kelce's Eras Tour performance

Taylor Swift is "swooning" over the fact her boyfriend Travis Kelce appeared on stage at one of her Eras Tour shows in London.

The 34-year-old chart superstar has been dating the Super Bowl-winning athlete since September last year and he has been supporting her world tour in various cities around the globe.

On Sunday night, the 34-year-old American football star joined Taylor on stage at Wembley Stadium where he carried her to a lip-shaped sofa before dancing on stage beside her.

The Shake It Off singer played three sell-out gigs over the weekend as part of her record-breaking eight-night residency at the iconic stadium, and she appears overjoyed with her success in London so far.

Taking to Instagram on Monday, the singer shared highlight photos and videos from her gigs alongside a gushing statement which read, "Wembley Stadium round one was so surreal. Looking out into crowds of 90,000 fans each night and hearing that VOLUME...

"Those were some of the loudest crowds I've ever heard. Acoustic sections went OFF."

Picking out highlights from her trilogy of nights, she continued, "I got to sing 'Castles Crumbling' with @yelyahwilliams (Paramore singer Hayley Williams) for the first time - hadn't performed with her since 2011 and man my heart was just so full of love for her and our friendship.

"Then the impossibly gifted and wonderful @gracieabrams came and surprised the crowd with the first performance of our song 'us.'"

And turning attention to her boyfriend, who she shared footage of on stage, she added, "And I'm still cracking up/swooning over @killatrav's Eras Tour debut Never going to forget these shows. Can't wait to do it 5 more times in August."
