Beyonce and Jay-Z have have lost their legal bid to trademark their 10-month-old daughter's name.
The couple had reportedly wanted to use Blue Ivy's name for a range of baby products, and had applied to the Patent Office in America to protect it from other users.
However, another company, a Boston event planning business, had been trading under the name since 2009.
CBS News reports that the US Patent and Trademark Office ruled in favour of the established company, and that Beyonce and Jay-Z have no legal rights over the name.
Last February, the Patent Office revealed it had already blocked two other attempts to trademark the name since Blue Ivy was born. They rejected the applications on the grounds the name belonged to a 'very famous infant'.
Wonder if they wish they had thought of an even more original name now? Purple Holly, perhaps?
Have you tried out your own version of Blue Ivy's name? The colour of your pants + your grandmother's name = Spotty Maud/Black Nelly and so on. What's yours?
