The party – which was held at Le Bam Studio in Atlanta, Georgia – was themed Minnie Mouse Clubhouse, and featured pink and purple decorations like a mouse-ear shaped balloon arch and a completely bedazzled highchair for the guest of honor.
Even Minnie, Mickey Mouse and Donald Duck stopped by for the family-friendly affair, which was planned by Bella Rose Events.
Heiress wore a sweet onesie and tutu designed by Lulu Bean Glam’s Sparkle Life, while the rest of the blended Harris family donned t-shirts denoting their relationship to the birthday girl and emblazoned with more mouse ears.

She adds, “It was so amazing to have all of her friends and family there to celebrate such a milestone. Heiress is our ‘lucky 7’ and has so much love around her. It was a great day!”
