Beyoncé Celebrates Tina Knowles’ Memoir Becoming a New York Times Bestseller: ‘I’m So Proud!’

Beyoncé is in proud daughter mode. After Tina Knowles‘ memoir, Matriarch, earned a coveted spot on The New York Times‘ bestseller list, the superstar took to Instagram to celebrate her mom’s accomplishment.

Sharing a poster announcing that “Matriarch is officially a No. 1 New York Times bestseller,” Bey wrote, “The Mama T was that good?? Ha.” The 35-time Grammy winner added, “You deserve it, I’m so proud!”

In the comments, the new author told her daughter, “Thankyou my baby,” with a heart emoji.

Knowles’ feat comes a little over a week after Matriarch hit shelves on April 22. This week, the memoir tops both the NYT‘s hardcover nonfiction and combined print & E-book nonfiction lists.

The businesswoman covers a lot of ground in the book, opening up about raising Bey and Solange from babies to two of the music industry’s biggest stars. At one point, she writes about navigating a particularly painful time in the “Texas Hold ‘Em” singer’s career: when rumors sparked that Bey was faking her pregnancy with Blue Ivy.

“This child was prayed for and prayed over — a wanted, cherished, real baby, and people were making a living off saying she was a lie,” Knowles wrote, noting how Bey had suffered multiple miscarriages before Blue came along. “I wanted to curse some people out and scream at these losers to set the record straight. They had no idea what she and Jay, and our whole family, had been through.”

The Cécred co-founder also opened up about the much more recent experience of receiving a breast cancer diagnosis last July. She underwent surgery in late 2024 to remove the tumor, recalling that Bey “took [the situation] well, staying positive … I could already feel her mind racing, focusing on this as a task to tackle with precision,” while Solange told Knowles, “We are going to take care of this.”
