Happy Birthday, Carole Middleton! The world's most famous mother-in-law and entrepreneur extraordinaire—your party-planning prowess has clearly paid off. After all, orchestrating royal weddings and grandchildren's birthdays must be a breeze compared to running your successful business empire!From building Party Pieces into an iconic British brand to gracefully navigating the spotlight as Catherine’s mum (and George, Charlotte, and Louis' beloved grandma), you've shown us how it's done with style—and perhaps a dash of humor too. May this birthday bring you plenty of cake (that someone else baked!) along with endless laughter surrounded by family who adore you dearly.
