Beyonce posted a handwritten Mother's Day note to her mom on her website.

"Everything I am is because of you!" the note reads. "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."

Jay-Z (real name Shawn Carter) and Beyonce welcomed their daughter Blue Ivy on January 7 in New York City.
