But just how thankful is she?
To answer that question, it's crucial to note there are basically two types of people in this world: those who send out thank-you notes and those who slip on a bikini and perform acrobatic stunts in the grass to show appreciation.
Queen Bey falls under the latter category, so the freshly minted 33-year-old took to Instagram with photographic proof her fans inspire her to defy gravity, a considerable feat of flexibility and flawlessness. (Note: If you want to copy said flawlessness, we found her Aerie bikini here, although we can't help you with the cartwheels.)
"Thank y'all so much for my birthday wishes!" wrote the singer, who marked the milestone Sept. 4 and was spotted celebrating with husband Jay Z in Portofino, Italy.
We're very pleased with her response, although we can't help but wonder what Blake Lively got for baking Beyoncé a birthday cake.
