Taylor Swift is expected to perform at the 2013 Victoria's Secret Fashion Show, which tapes this week, the New York Post reports. Swift could amp up the event's drama by glaring at veteran Angel Cara Delevingne when she sings "I Knew You Were Trouble," purportedly about their mutual ex Harry Styles. (If Delevingne walks, that is.) Or she could hand Delevingne the mic for a few bars in a viral show of #sisterhood. Who knows! You'd have to be pretty immune to the threat of female competition to perform in such close proximity to Victoria's Secret models in the first place.
