AceShowbiz - Rihanna is planning to release a Caribbean cookbook.
Documents filed by her Roraj Trade firm with the U.S. Patent and Trademark Office show the star has trademarked the term "Sorry, I'm Booked" for use selling cookbooks and online publications.
According to British newspaper The Sun, the new book will feature some of the Bajan superstar's favourite Caribbean recipes.
A source tells the tabloid: "Rihanna's always been a fan of good food and during lockdown she worked up plans for bringing out her own book. It will include some of her favourite Caribbean recipes.
"The dream would be to bring out her own range of kitchenware too. Rihanna has proven that, as well as being a best-selling artist, she is a savvy businesswoman and those around her think this next step could be a huge hit."
Intriguingly, the trademark also covers, "science fiction, adventure, mystery, history, action, drama, documentary content, comedy, horror, romance, music, children's entertainment and thrillers," meaning the "Umbrella" hitmaker may be planning more than a traditional recipe tome.
It is also registered for use selling bowls, plates, pots, pans, utensils for barbecues, forks, tongs, turners, and aprons, as well as condiments like hot sauce.
The star has already enjoyed huge success with her Fenty beauty and clothing ranges in addition to her music, amassing a fortune estimated to be worth more than $588 million (£450 million), despite not releasing an album since 2016's "Anti".
