Deluxe copies of Katy Perry’s latest album can't be "imported" into Australia, as the seed paper used in the high-end version of "Prism" has been deemed a biosecurity concern by officials there.

The 29-year-old singer, who has been encouraging her fans on Twitter to enjoy the colors of her album, included seed paper in the deluxe album with the hope that fans would plant the paper and “spread the light.” Seed paper is a handmade paper containing plant seeds that can grow when the paper is planted. While the purpose is tame enough, officials Down Under are concerned that copies bought overseas may contain plant seeds foreign to Australia, thereby presenting an international security issue. Albums bought in Australia contain Swan River daisy seeds, which are not considered a biosecurity concern.

“Seeds or plant material of international origin may be a weed not present in Australia or the host of a plant pathogen of biosecurity concern,” a spokesperson told news.com.au regarding the seed paper. “Our biosecurity officers at international airports, seaports and mail centres [sic] assess the risks associated with various items every day and are well-trained in making informed decisions about whether items could be of biosecurity concern."

Meanwhile, in addition to releasing her album, Perry has plenty of reason to celebrate these days. This week, she dethroned Justin Bieber as the person on Twitter with the most followers. Perry has an astounding 46.5 million followers, surpassing Bieber by 200,000. After the feat, Perry shared some social media tips with USA Today, saying, “I’ve learned how to ride social media. I have horrible typos. I use ‘there’ or ‘your’ wrong grammatically. But I feel like I’ve learned how to tame that social media dragon.” And her No. 1 rule? "Less is more."
