Jessica Simpson has paid a heartfelt birthday tribute to her mother

Jessica wrote on X: "Happy Birthday to my Mommy- the giver of abundance, love, passion, and purpose. Your light is the brightest of all-assembled by the multitudes of your individual blessings that create iridescent and unique sparks! Not only does your glow make you shine, but there is an honesty within your heart that gives truth to divine ambition and a courageous certainty that represents how passion can lead to unparalleled greatness.

"As your first born, I can say exactly what I need to say, be entirely who I am, love selflessly without fear or expectation and always find ways to think outside of the box to solve any problem at any given time because you are my guide and have shown me the beauty in the how. Many of these things cannot be taught with words- only through leadership and action. (sic)"

Jessica also confessed to feeling inspired by her mom's "example".

The pop star wrote on the micro-blogging platform: "There is no stopping YOU when you believe in something with all of your heart. I am so lucky to be something and someone you believe in. When there is responsibility, commitment, determination, and integrity required YOU ARE THE GOAT [heart emoji]

"every single sunrise and sunset and especially on a full moon there's nobody in this world I'd rather be loved by than you. I love to love you, make you proud, hug you and work alongside you each and every day for eternity! Thank you for making me a priority and for always giving me the no matter what kind of love! (sic)"
