Proof That Taylor Swift Is The Ultimate Wedding Crasher

Taylor SwiftandCalvin Harris may have called it quits, but the country singer-turned-pop star still believes in love.

On Saturday night, Swift went back to what she does (second) best: surprising fans. She crashed the wedding of one happy bride and groom, Max Singer and Kenya Smith, with a special performance of her hit "Blank Space." Swift played the song on the piano as the couple shared a dance. One guest managed to capture a clip of the performance and share iton Twitter.

"So, Taylor Swift showed up to my cousins wedding... #surprised," Gage Simmons tweeted.

For one person, the groom's sister Ali, the performance wasn't a surprise at all -- it was the outcome of some serious planning. According to People, Ali and TSwift coordinated the appearance for months afterAli reached out to the "22" singerwith a heartfelt letter.

Ali told Swift that she and Max had lost their mother, and explained how Max and Kenya previously got married at the hospital so their mom could witness the special day, People reported. Max and his mom did their mother-son dance to “Blank Space.”

Aside from performing for the newlywed couple, Swift took some time to pose for photos with them and their guests.

She even made Max and Kenya a personalized gift:

Of course, this wasn't Swift's first rodeo -- she's basicallythe ultimate wedding crasher.

Nicely done, TSwift.
