The VSFS 2017 show is going to stream by Tencent, one of China’s biggest media companies. They put out a commercial on the upcoming show and Taylor Swift is one of the performers. The ad is in Mandarin (of course), on Taylor’s part they mentioned it’s her 3rd time doing the show.
No official news from VS yet but this sort of confirms Tay’s performance.
Thanks to a special friend for giving me this info.
