There are all kinds of symbols attached to the superstar’s latest trip around the sun

In case you didn’t know, today is a holiday. No, nothing on the national calendar, but it is Beyoncé’s birthday.

That’s right, today the musical superstar, mom of three, Grammy record holder, and haircare/whisky mogul celebrates her 44th—which is a particularly special occasion. It’s not a traditional milestone, but there’s a chance that Queen Bey’s been counting down to this day, given that four is her lucky number.

Why is it lucky? Well, it all starts with the fact that Beyonce’s birthday takes place on September 4. Not only that, but the number pops up in the birthdays of a couple important people in her life, including husband Jay-Z (who was born on December 4) and her mom, Tina Knowles (who was born on January 4).

Not to mention, Beyoncé and Jay-Z actually got married on April 4, 2008 (the fourth day of the fourth month), and to commemorate the date, the two got matching “4” tattoos on their ring fingers. Years later, Beyoncé had hers altered so that it looked like a fusion of a numeral four, as well as the letter “J,” as a wink to her husband.

Even when Bey and Jay-Z’s first daughter was born, they gave her the name Blue Ivy (because “Ivy” could phonetically represent the Roman numeral IV—get it?)

The connections don’t end there, though. When she released her fourth studio album, Beyoncé fittingly titled it 4, and her husband followed suit when he named his next album 4:44.

And the symbols just keep on going. When Destiny’s Child was formed, there were originally four members. When Beyoncé posed for a Tiffany & Co. campaign in 2018, she became the fourth woman in history to wear the rare 128-carat Tiffany yellow diamond, after Mary Whitehouse, Audrey Hepburn, and Lady Gaga.

So, how is Beyoncé celebrating her special day? Typically, the singer keeps her private life out of the spotlight, and it’s notable to mention that this morning, her longtime collaborator and designer, Giorgio Armani, passed away. Due to this, she may be staying off social media in order to pay respect to his loved ones.

It’s also possible that she is merely enjoying her birthday and staying offline. Cheers to you and your 44th, Bey.
