LOS ANGELES, Calif. -- Beyonce became a mom in January (welcoming daughter Blue Ivy Carter with husband Jay-Z), but the superstar celebrated her first Mothers Day by giving credit to her own mom, Tina Knowles.

The singer penned a handwritten note to her mom (which was shared on her personal website in a post titled Dear Mama), thanking Tina for giving her an excellent parental role model to look up to as she raises little Blue.

Everything I am is because of you, the note, posted on Sunday read. 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, the note continued. Now that Im a mother, I truly realize all the sacrifices you made for us. My love for you goes beyond what I can say. Happy Happy Mamas Day. Love, Beyonce.
