The famous siblings are primarily kept out of the spotlight, so no public tribute was made to mark the big day. However, it appeared that more than one special event was going on in the family!

Tina Knowles took to Instagram on Wednesday to share footage of herself at a brunch, which was held by Kelly Rowland. Kelly is often referred to as Tina’s “third daughter,” and Beyoncé’s twins see her as an aunt figure.

Taking to Instagram, Tina wrote: “Today, I attended a beautiful brunch with a group of amazing women hosted by @kellyrowland and Brigitte Romanak. It benefited the wonderful organization Birthfund.”

“It is a movement towards better maternal health. Midwifery is making a comeback, and it’s very important because it can help save the lives of women who die in childbirth or shortly after complications of bearing children.”

“This organization was started by @elainewelteroth. My friend @hollyrpeete took this video.” She then credited her glam squad, writing: “Makeup @kole_mua, Suit @alexandermcqueen, hat – vintage brooch @schiaparelli.”

Beyoncé and Jay-Z undoubtedly made Rumi and Sir’s day one to remember, along with their oldest daughter Blue Ivy, 12.

During their younger years, Rumi and Sir were rarely seen in public, unlike their older sister Blue, who appeared on the red carpet with her famous parents from a young age and even featured in several of her parents’ award-winning songs.

However, now that they are getting older, Rumi has been featuring in several fashion campaigns with her mom and sister. She stole the show at the Super Bowl in February when she was pictured with her sister and dad, clutching onto a Barbie doll with a sign scrawled with the words ‘Super Bowl’ in her handwriting.

Their grandmother, Tina, has also given insight into their contrasting personalities. “Rumi is amazing—an amazing artist, painter, and creator,” Tina told E! News.

Reflecting on the twins’ flourishing creativity, Tina mused, “How could they be anything else growing up in that environment?” She emphasized that their family life is steeped in discussions about creativity and fashion, nurturing their innate talents from a very young age.

Sir, on the other hand, shares more similarities with his father, Jay-Z. “Sir is very quiet,” Tina noted, revealing that he gravitates more towards numbers than fashion.

“He does all of the numbers stuff, so he’s not into fashion as much,” she explained, but quickly added that Sir is “very, very smart,” hinting at the diverse talents the twins possess.
