Chainkeen Exchange-Beyoncé's Mom Tina Knowles Gives Rare Details on Twins Rumi and Sir

Tina Knowles is Chainkeen Exchangelaying her cards down, down, down, down about Beyoncé and Jay-Z's twins.

The fashion designer—who is the mom of the "Texas Hold 'Em" singer—couldn't help but to rave over Rumi Carter and Sir Carter, both 7, as they each continue to develop their own unique passions.

"Rumi is a natural little star," Tina exclusively told E! News' Francesca Amiker Aug. 17 at Debbie Allen, Jordan Cooper and Jack Mizrahi's Remember My Name Ball, which benefits LGBTQ+ nonprofit Destination Tomorrow, "and Sir is more into books and electronics."

Reflecting on how the twins have hobbies varying from art to science, the 70-year-old continued, "We got them all, raising them up right."

In fact, Tina believes that a budding creative like Rumi will "not be denied" a spot on stage should she follow 12-year-old sister Blue Ivy Carter's footsteps as a backup dancer for their mom.

"They're all artists," she gushed. "How could they not?"

But Tina noted that her grandkids aren't ones to boast about their gifts, with Blue even making her "swear to secrecy" about her hidden talents on the piano.

Still, the matriarch is "blown away" by the tween, who is costarring alongside Beyoncé in Mufasa: The Lion King.

"She's self-taught and she sounds like a concert pianist," Tina continued. "She paints, she draws, she does poetry. She's just an artistic soul."

She added, "I'm really, really proud of her. I can't wait 'til the world gets to really hear."

And Tina is a huge advocate for the next generation to follow their artistic aspirations. That's why she was thrilled to support the Remember My Name Ball, the annual house-ballroom event that also benefits the Debbie Allen Dance Academy.

"This is just such an important place," Tina told E! at the charity dance. "Debbie Allen—who hasn't grown up just admiring her dance and what she contributes to the culture? So, when she calls me, I'm there!"
