The '22' singer vied for the spotlight in a glitzy minidress as she walked the pink carpet before the event, held at the Lexington Avenue Armory in New York.
Taylor looked pretty as a picture in her glimmering sequin number, designed by Zuhair Murad, which was covered in stunning beaded flowers.
She topped her sunkissed limbs with forest green peep-toe heels while styling her honey locks in a smooth and sleek 'do.
The starlet let her glamorous frock do all the talking by keeping her nails bare and her jewellery minimal, simply wearing two gemstone rings.
After making her smouldering entrance Taylor then changed into a Union Jack dress, before donning a bejewelled silver number to perform her tune 'I Knew You Were Trouble'.
She even got to walk alongside the models while they strutted their stuff - jealous!
Clearly on a high, the songstress later tweeted: "Tonight!! Insane! Glittery catwalk! IS THIS REAL LIFE @LilyAldridge @VictoriasSecret #VSFashionShow."
Sounds like every girl's dream!
