Happy Birthday To The Queen, Beyonce' Turns 44 Today.

The Queen is turning 44! And for a global superstar who's long used the number four as her personal calling card, this isn't just any birthday—it's a major milestone. Beyoncé's been keeping the Beyhive on the edge of their seats, as she's known for dropping bombshells when we least expect them. So with her birthday on September 4th, the buzz is palpable: What's she going to do next?

This isn't a new obsession. Over the years, the number four has shown up everywhere in Bey and Jay-Z's lives. It's a cosmic connection they've celebrated again and again.

• Both Beyoncé and Jay-Z were born on the fourth of the month.

• Bey's mother, Tina Knowles, also has a birthday on the fourth.

• The power couple made it official on April 4, 2008.

And if you thought that was a coincidence, think again. Beyoncé named her fourth studio album 4 and the live concert film Live at Roseland: Elements of 4. She even has a tattoo of the Roman numeral IV on her ring finger, a match to Jay-Z's. Later, he even titled his 13th studio album 4:44 as a nod to their relationship.

And of course, we can't forget their firstborn daughter, Blue Ivy. The name "Ivy" is a direct reference to the Roman numeral for four. Even her activewear line with Adidas was called Ivy Park.

The legend of the number four has grown so deep that even when she's talking about one of her proudest moments—singing at Barack Obama's inauguration—she can't help but connect it back to her lucky number. In a past concert film, she pointed out that Obama was the 44th President and his birthday is on the fourth of the month. As she famously said, with a little playful numerology: "on April 4, 2008—eight divided by two is four—[Jay-Z] put a ring on it."
