One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
Holy shizz, Taylor Swift is on FIRE tonight!
The 23-year-old got up on stage to perform her hit I Knew You Were Trouble and rocked two STUNNING outfits.
Swifty began her performance in an embroidered white bridal gown with a voluminous structured skirt before having it RIPPED off by her male dancers to reveal black hot pants and seksi lace bustier top!
We imagine Harry's eyebrows reached all the way up to his hairline! Ha!
