Taylor Swift is feeling all the feels after her beau, Travis Kelce, joined her onstage Sunday during the Eras Tour.

On Monday, the “Bad Blood” singer took to Instagram to reflect on her three-show run at London’s Wembley Stadium, which began on Friday. One of the biggest highlights came on night three when the Kansas City Chiefs tight end surprised the crowd when he joined her onstage.

“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,” the 34-year-old singer wrote. “Acoustic sections went OFF. I got to sing ‘Castles Crumbling’ with @yelyahwilliams 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.’”
