Taylor Swift Performs Calvin Harris' 'This is What You Came For' at Formula One Concert

Taylor Swift sparkles on stage while performing her only scheduled concert date this year during the Formula 1 United States Grand Prix at Circuit of The Americas on Saturday night (October 22) Austin, Texas.

The 26-year-old singer delighted around 80,000 fans with her first-ever live performance of the Calvin Harris/Rihanna song “This Is What You Came For,” which Taylor co-wrote – and she played it on the piano!

“Welcome to F1 on a Saturday night,” Taylor told the crowd (via E! News). “As a songwriter, the most rewarding feeling in the world is writing something and having a crowd sing it back to you because you know the words. I never played this song live before, but you know it. Maybe you can sing along.”

Taylor also sang hits like “We Are Never Ever Getting Back Together,” “Fifteen,” “You Belong With Me,” “New Romantics,” “22,” and more!
