Photos: Beyoncé and Jay Z through the years

Jay-Z and Beyoncé sang her single “Crazy in Love,” which featured Jay-Z at the 2003 MTV Video Music Awards at Radio City Music Hall on August 28, 2003, in New York City.

When she broke off from Destiny’s Child, she was first featured on Jay-Z’s single “03 Bonnie & Clyde” about a runaway love affair. Later the two collaborated on her “Crazy in Love,” which gave rise to her alter-ego, Sasha Fierce.

“You know we were friends first for a year and a half before we went on any date on the phone for a year and a half,” she told Oprah Winfrey. “And that foundation is so important in a relationship. And just to have someone that you just like is so important and someone that is honest.”  (Frank Micelotta / Getty Images / Courtesy)

On January 7, 2012, she gave birth to their daughter, Blue Ivy Carter, at Lenox Hill Hospital in New York.

The music moguls haven’t offered a direct explanation of the name choice but Bey did share a limerick on her website that potentially clarified the choice. They added on “Ivy” because of the significance of the number 4 -- or IV. Both of them were born on the 4th of their respective birth months and the couple was married on April 4, 2008.

A few days after she was born, Jay-Z dedicated the song “Glory” to his daughter and the track featured her cries, so he credited her as “B.I.C.”  ( Ed Burke for Beyonce.com / Associated Press / Courtesy)

Beyoncé infamously used a pre-recorded track during her performance of the national anthem, which piqued the interest of many leading up to her halftime show performance at Super Bowl XLVII.

She later kicked off a Super Bowl press conference in New Orleans belting out the national anthem. She then confirmed her use of the pre-recorded track during the inauguration because she was a “perfectionist,” adding that she “absolutely” planned to sing live during the Super Bowl halftime show. And she did.  (Win McNamee / Associated Press / Courtesy)

After winning the Grammy Award for rap-sung collaboration for “Holy Grail,” his track with Justin Timberlake from his “Magna Carta Holy Grail” album, Hova took the stage to praise his wife and daughter, Blue Ivy.

“I want to thank God, I mean, a little bit for this award, but also all the universe for conspiring and for putting that beautiful light of a young lady in my life,” the rapper said. Then he tipped his gilded gramophone on it side and added, “I want to tell Blue, ‘Look, Daddy got a gold sippy cup for you!’”   (Robert Gauthier / Los Angeles Times / Courtesy)
