"How is my first born, best news of my life, and best friend already 10yrs old?!? We had a magical weekend following her lead of rotating friends and family. She begged God to not grow up and to wake up 5yrs old again," Simpson began. "She told everyone that she turned 5 and it filled my heart with so much gratitude for this beautiful and precious LOVER OF LIFE," she added, describing Maxwell as "a leader without ego" and "a bleeding heart that inspires and loves deeply and forever," among a slew of other compliments.
