This is what the Taylor Swift fans could only hope for when they decided to come to tonight's show.
"Welcome to F1 on a Saturday night," the audibly beloved star welcomed close to 80,000 screaming fans as she strutted across the stage in a short, black, sparkly number.
During her first and only concert performance of 2016, Formula 1 U.S. Grand Prix weekend in Austin, Texas, the Grammy winner tore through a number of her hits—but the cherry on top may have been a stripped-down version of "This Is What You Came For," the track Swift co-wrote for then-boyfriend Calvin Harristhat became a huge, song-of-the-summer hit for the Scottish DJ-producer and Rihanna.
Taylor's backing vocals can be heard on the single, and she did a little lip-syncing during New York Fashion Week, but this was the first time she's publicly performed the tune start to finish. The Internet was set ablaze with anticipation earlier in the day after video of her rehearsing at a piano during a sound check made the rounds.
