Selena Gomez
and a group of her best friends choreographed an incredible dance routine to Taylor Swift's latest single "I Knew You Were Trouble!"

Selena's vido was released yesterday, the same day as the song's music video, and also the day of Taylor's 23rd birthday! We hope Taylor liked her birthday surprise!
