A bona fide superstar will sing at Alibaba’s annual shopping extravaganza next month — and for once it won’t be Jack Ma.

Okay, so there’s no guarantee that the e-commerce giant’s limelight-loving former chairman won’t also treat audiences to a song. But if he does, he’ll have to make room for U.S. pop icon Taylor Swift.

The “You Need to Calm Down” singer will perform on Nov. 10 at Alibaba’s 11.11 Countdown Gala, an annual live show that runs in the hours leading up to the so-called Double 11 shopping festival, Alibaba announced Monday. The gala, which also features a host of local and international celebrities, will take place at Shanghai’s Mercedes-Benz Arena and be broadcast live both on TV and online.

With her fondness for songs about heartbreak, Swift is an apt choice of performer for a festival also known as “Singles Day,” the world’s biggest one-day shopping event. Last year, it generated $30.8 billion in gross merchandise volume, more than the combined U.S. revenues of Thanksgiving Day and the weekend encompassing Black Friday and Cyber Monday.

Since its inception 11 years ago, Double 11 has morphed from a straightforward celebration of discounted shopping to a wall-to-wall celebration of consumerism that’s virtually impossible to shake off. This year, more than 500 million users and 200,000 brands are expected to participate in the event.
