On Tuesday, Jessica Simpson marked her eldest daughter Maxwell's 10th birthday with a touching tribute.

The 41-year-old also shares 8-year-old Ace Knute and a 3-year-old, Birdie Mae, with her husband, Eric Johnson.

Simpson credited Maxwell for leading others without ego and having a heart that inspires and loves deeply.

The proud mother tributed her daughter as "thought provoking, ahead of the curve, resilient, prayerful" and more.

Simpson discussed her daughter's heart illuminating into heaven when they pray before bed.

The matriarch gushed, "Maxwell Drew Johnson is THE PERFECT 10 and my VERY BEST FRIEND!!!"

The 10-year-old celebrated her birthday with family and friends, including North West and Penelope Disick.

In April, Simpson spoke on having her card declined at Taco Bell while on a budget and awaiting a new card.

The mother-of-three credited her resolve to running her reclaimed multi-million dollar business, the Jessica Simpson Collection.
