Pop singer Christina Aguilera has filed trademarks related to non-fungible tokens and the Metaverse with the United States Patent and Trademark Office.

The "Genie in a Bottle" singer wants to create downloadable multimedia files containing artwork, audio, text and videos relating to music and the performing arts. Such files would be authenticated with the help of non-fungible tokens.

The pop diva plans to offer a slew of virtual goods such as art, clothing, headwear, footwear, eyewear, beauty products and other virtual merchandise.

Aguilera also wants to provide entertainment services such as musical performances and virtual appearances.

The pop singer gained popularity in the late 1990s with her self-titled debut album that sold roughly 14 million copies worldwide. The 1999 release, which spawned several sizeable hits, has been certified 8X platinum in the U.S. Aguilera, however, fell short of matching the massive sales of her then-rival Britney Spears, who boasts two diamond-certified albums.
