The 43-year-old Grammy-winning artist took the stage at SoFi Stadium in Los Angeles on Thursday, May 1, for the second stop on her global Cowboy Carter Tour.

After a performance of her Cowboy Carter song “Protector” — where she was joined onstage by daughters Blue Ivy, 13, and Rumi, 7 — the audience erupted into cheers as Knowles walked out.

The three generations of women in the family stood together arm-in-arm, and Beyoncé used the moment to praise her mom, 71, on the success of her new memoir Matriarch.

Today is a big day because my mother, who worked so hard on her book, she has the No. 1 book on the New York Times bestsellers,” the singer said, urging the audience to join her in a chorus of “Congratulations, Mama T.”
