Grammy-winning singer Beyonce Knowles-Carter is one of many entertainers celebrating Mother’s Day this weekend and has inked an open letter to her mother Tina Knowles.

In the letter, Bey thanks her mom for providing motivation and confidence in who she is as a woman.

“Dear Mama,

Everything I am is Because of you! You are the first voice that ever sang to me. At every turn you push me to be better. You teach me to be true to myself and the ones I love. When I look into your eyes, I am sooo proud. Now that I’m a mother, I truly realize all the sacrifices you made for us. My love for you goes Beyond what I can say. Happy Happy Mama’s Day! Love, Beyonce. (Beyonce)

Earler this year, Tina Knowles spoke on becoming a grandmother to Bey and rap star Jay-Z‘s newborn daughter, Blue Ivy.

Beyoncé and Jay-Z’s newborn daughter Blue Ivy is already charming all the right people, including her grandma. “She’s doing great,” a beaming Tina Knowles told PEOPLE at the Runway to Win fundraising reception for Barack Obama in New York. “She’s beautiful.” As for her duties as a doting grandma, Knowles calls them “amazing,” adding, “It’s the second best job I’ve ever had.” Although her adoration for the new addition to her family was certainly instantaneous, Knowles is waiting to decide which parent little Blue resembles most. “She’s only a month old,” she says. “So we have to give her a minute.” (PEOPLE)

Last month, Bey penned a letter to First Lady of the White House Michelle Obama.

“Michelle, is the ULTIMATE example of a truly strong African American woman. She is a caring mother, she’s a loving wife, while at the same time, she is the FIRST LADY!!!! No matter the pressure, and the stress of being under the microscope – she’s humble, loving, and sincere. She builds and nurtures her family, while also looking out for so many millions in so many ways. Michelle, thank you so much for every single thing that u do for us – I am proud to have my daughter grow up in a world where she has people like you to look up to. Love, Beyonce.” (Beyonce)

This was later met with praise and admiration from Mrs. Obama.

“@Beyonce Thank you for the beautiful letter and for being a role model who kids everywhere can look up to. -mo,” she tweeted April 13th.
