Let's make this birthday one to remember.

35 years old (Born on December 28, 1989)

Happy Birthday, Mackenzie Rosman! From charming us all as the adorable Ruthie Camden on "7th Heaven," you've grown up gracefully right before our eyes. Your mischievous smile and heartfelt performances made family drama feel relatable—and let's be honest, you single-handedly taught a generation how to navigate sibling rivalry with sass and style.

As you celebrate another fantastic year, we applaud your journey beyond childhood stardom into new adventures. Whether you're riding horses or championing important causes, your authenticity shines through. Here's hoping this birthday brings laughter, cake (lots of it!), and endless reruns reminding everyone why Ruthie was always secretly everyone's favorite Camden kid!
