Katy Perry was reportedly "banned indefinitely" from China ahead of her rumored performance at the Victoria's Secret Fashion Show taking place next Monday in Shanghai, the Daily Mail reports.
Page Six reported Thursday that Chinese authorities denied the 33-year-old pop diva's visa after outrage over her wearing the Taiwanese flag during a 2015 concert at Taipei Arena.
The communist country was further angered over her wearing a sunflower gown - symbolic of the Sunflower Student Movement, which protested a Chinese trade agreement in 2014.
"She was initially granted a visa to perform at the VS show in Shanghai, then Chinese officials changed their minds and yanked her visa," a source told the site.
"For every artist who wants to perform in China, officials comb through their social media and press reports to see if they have done anything deemed to be offensive to the country. Maroon 5 was banned a few years ago because one band member wished the Dalai Lama happy birthday on Twitter."
