Before the stroke of midnight on Sept. 4,, Tina Knowles-Lawson was one of the first people to wish her “firstborn,” Beyoncé, a very happy 37th birthday with a throwback baby photo and heartfelt message.

“It’s already your birthday where you are [heart emoji] So Happy Birthday to the nicest, owner of the most beautiful, generous, loving hearts ever !!!! Brilliant too! Always thinking, planning, analyzing, [strategizing], how you can make everything you touch better!” Knowles-Lawson wrote under a picture of a 4-month-old Beyoncé.

The mother of two went on to express the joy she felt raising the pop star and her younger sister, Solange. “Sometimes I can’t believe out of all the incredible people in the world I was chosen by God to be your mom!” Knowles-Lawson continued, “The day that you and your sister entered this world were the two best days of my life, hands down!! It is a privilege to have carried you two in this body  Enjoy your B-Day !!! No one deserves it more!! I love you Mom.”
