And in her sparkly minidress and sky-high heels, Taylor looks like an honorary Angel herself!
The singer performed "I Knew You Were Trouble" as models like Candice Swanepoel and Karlie Kloss worked the catwalk and it's clear she had a fabulous time.
Tay even made friends with Cara Delevingne, a model that her ex Harry Styles has been linked to repeatedly.
She shared a photo of herself, Cara, Lily Aldridge and Erin Heatherson cuddled up backstage with the caption: "Best friends forever."
Taylor even playfully swatted Cara's butt when she walked by her on the runway.
