Mamma’s taught her well!

Proud mum Jessica Simpson was celebrating her daughter Maxwell’s 5^th birthday over the weekend and took to social media to share some of the glorious images from the big event. The mermaid-themed party was all sorts of goals, with the amazing under-the-sea decorations and Maxwell’s amazing mermaid costume.

The birthday girl looked to be having a great time as she donned her sequin mermaid tale and matching seashell top. But we can’t help but notice Maxwell and Jessica's twin pose - hand-on-hip, it's a classic! With their best side on show, Maxwell and Jessica, alongside dad and brother, three-year-old Ace, posed for a family portrait that definitely deserves a place on the mantelpiece.

My baby Maxwell is 5 years old today. She makes everyone's life mermaid magical. Happy Birthday to our fairytale princess. Mommy, Daddy, and Ace love you with our "holy hearts" (as Max would say) #MerMax #MAXIDREW #canyoube5forever
