Let's make this birthday one to remember.

31 years old (Born on April 16, 1994)

Happy Birthday, Liliana Mumy! From charming us as Jessica Baker in "Cheaper by the Dozen" to bringing holiday cheer (and mischief!) as Lucy Miller in "The Santa Clause 2 & 3," you've always had a knack for stealing scenes and hearts alike. Your comedic timing made family chaos look effortlessly hilarious—something we all secretly envy.

Whether you're navigating sibling antics or helping save Christmas from disaster, your roles have become timeless favorites that still make audiences laugh today. Here's hoping your birthday is filled with fewer chaotic siblings than on-screen—but just enough fun to keep things interesting!
