Beyonce looked chic as ever with a metallic bodice and matching shades.
In a post on her Instagram, Swift paid a gushing tribute to the icon.
“I’m so glad I’ll never know what my life would’ve been like without @beyonce’s influence,” she said.
“The way she’s taught me and every artist out here to break rules and defy industry norms. Her generosity of spirit. Her resilience and versatility. She’s been a guiding light throughout my career and the fact that she showed up tonight was like an actual fairytale.”
