The 2017 Victoria’s Secret Fashion Show is turning out to be a less than heavenly spectacle amid several last-minute changes, including cutting headline performer Katy Perry just days before the event.

Page Six reported that Perry was set to perform at the Nov. 20 show in Shanghai, China, but was suddenly banned indefinitely from the Asian nation after Chinese officials discovered the singer had worn a bright, glittery dress with sunflowers on it in 2015 in Taiwan.

Anti-China protesters had adopted the sunflower as their symbol the year before, according to Page Six, so her outfit was offensive to the communist country. Singer Harry Styles of One Direction fame is expected to replace Perry.

Additionally, four of the lingerie giant's supermodels were denied entry into China just ahead of the show.

Julia Belyakova, Kate Grigorieva and Irina Sharipova from Russia, in addition to Dasha Khlystun from Ukraine, reportedly cannot enter the country due to visa issues, Fashonista first reported.

What's more, model Adriana Lima's visa is allegedly held up due to a "dimplomatic problem," according to Page Six.

Viewers will be able to watch the Victoria’s Secret Angels and other models on the catwalk, and take in several musical performances.

Here’s what you should know about the fashion show, set to take place in Shanghai, China on Nov. 20.

The Victoria’s Secret Fashion Show will be shown on Tuesday, Nov. 28 at 10 p.m. ET on CBS.

“Merging fashion, fantasy and entertainment, the lingerie runway show will include pink carpet interviews, model profiles, a behind-the-scenes look at the making of the show and musical performances that will be announced at a later date,” a release said.

Though performers have yet to be revealed, it’s safe to expect some big names; Bruno Mars, Lady Gaga and The Weeknd all performed at the 2016 show.

"Love my VS family, and will be with all my girls in spirit!!"
