Emergency Delivery: The situation became life-threatening for both mother and children, necessitating an emergency C-section.

Weeks in the NICU: Following the delivery, the newborns had to spend several weeks in the neonatal intensive care unit (NICU). Beyoncé revealed that one of the twins' hearts even stopped during the birth, highlighting the gravity of the situation.

The Surprising Meaning Behind Their Unique Names

Unlike their older sister, Blue Ivy, whose name is often speculated to be a reference to Jay-Z’s “The Blueprint” albums, the names Rumi and Sir have much more distinct and personal inspirations, revealed by Jay-Z himself.

Rumi Carter: Named After a Beloved Poet. Their daughter, Rumi, is named after the 13th-century Persian poet, Jalāl ad-Dīn Muhammad Rūmī. The couple shares a deep admiration for the poet’s work, which is known for its mystical, passionate, and often spiritual themes. The name Rumi is also said to mean "beauty, flow, lapis lazuli" in Japanese, a symbolic nod to the "brilliant blue" gemstone.

Sir Carter: Named for His Presence. The story behind their son, Sir, is much simpler and more spontaneous. Jay-Z explained that Sir earned his name through his demeanor immediately after birth. "Sir was like, man, come out, like, Sir," he said. "Sir just came out, like, 'Sir.' So, he got a name before he even came out of the womb, almost."

Rumi vs. Sir: A Look at Their Distinct Personalities

Despite being twins, Rumi and Sir have developed strikingly different temperaments, a fact their mother and grandmother, Tina Knowles-Lawson, have shared in rare public comments.

Rumi: The Bossy, Artistic Twin. Rumi is consistently described as the more outgoing, artistic, and assertive of the two. Tina Knowles-Lawson once shared that Rumi is "the boss" and "very artistic," often showing a flair for fashion and a tendency to take charge, much like her superstar mother.

Sir: The Reserved, Chill Twin. Sir, on the other hand, is the quiet observer. He is often described as reserved, chill, and cool—a personality that mirrors his father, Jay-Z. Beyoncé herself has noted the distinct difference, with Sir being the more subdued twin.

These contrasting personalities explain their differing levels of public visibility. Rumi has been seen more often, including a notable appearance with her father and sister at the 2024 Super Bowl and in promotional materials for the Cowboy Carter album era. Sir is rarely seen in public, maintaining the highest level of privacy among the three Carter children.

Growing Up Carter: Life in the World’s Most Famous Family

As Rumi and Sir enter their elementary school years, their lives are a balance between extreme wealth and privilege and a concerted effort by their parents to provide a normal upbringing. The family splits their time between their homes in Los Angeles and New York, offering a cosmopolitan upbringing.

Mentorship from Blue Ivy: The twins are constantly guided by their older sister, Blue Ivy, who has become a global figure in her own right, performing on the Renaissance World Tour and attending major events. This mentorship ensures the twins are growing up with a strong, grounded figure who understands the demands of their family’s fame.

Future in Music: While it is too early to tell if Rumi and Sir will follow in their parents' footsteps, Rumi has already made a subtle mark. She holds a unique distinction as the youngest female artist to ever chart on the Billboard Hot 100, thanks to a feature on her mother's song "BROWN SKIN GIRL."

The twins’ journey is a testament to the Carter family’s commitment to legacy, privacy, and carefully curated public image. As they grow older, the world will undoubtedly watch to see how Rumi, the boss, and Sir, the gentleman, shape their own narratives within the most influential family in music.
