Jessica Simpson’s Daughter Maxwell Celebrates 10th Birthday with North West and Penelope

The big 1-0! Jessica Simpson’s daughter Maxwell Johnson hit double digits over the weekend and celebrated her 10th birthday with some famous friends! 

“How is my first born, best news of my life, and best friend already 10yrs old?!?,” Jessica, 41, wrote alongside a photo of Max that the singer shared via Instagram on Tuesday, May 3. “She begged God to not grow up and to wake up 5 years old again. She told everyone that she turned 5 and it filled my heart with so much gratitude for this beautiful and precious LOVER OF LIFE.”

Jessica – who, in addition to daughter Maxwell, shares son Ace Knute, 8, and daughter Birdie Mae, 3, with husband Eric Johnson – threw her oldest daughter a magical outdoor movie night party. 

The “Take My Breath Away” singer shared photos of the extravagant event which was attended by famous pals North West and Penelope Disick. A truck full of Squishmallows, a giant projector screen, whimsical balloon garland and comfy floor cushions can be seen throughout the backyard party. 

Kim Kardashian and Kourtney Kardashian’s daughters looked thrilled to be celebrating their pal’s birthday! The trio were spotted in the back of a pickup truck, surrounded by the stuffed toys, while Maxi opened her gifts.
