Let's make this birthday one to remember.

25 years old (Born on February 20, 2000)

Happy Birthday, Sierra! Another year older and still effortlessly stealing the spotlight from Jacob—seriously, how do you manage to outshine a YouTube star without even trying? Your tweets alone deserve their own fan club; they're funnier than any viral video your brother could ever post.

From your hilarious commentary on life's daily adventures to celebrating recent successes with style and grace, you've truly become everyone's favorite Whitesides sibling (sorry Jacob!). Here's hoping this birthday brings as much joy as that time you casually broke Twitter with one witty comeback. Keep shining bright—you've officially mastered the art of being timelessly fabulous!
