Reese Witherspoon Wished Her Son Deacon a Happy 16th Birthday, and They're So Cute Together

If you follow Reese Witherspoon on Instagram, you probably already know that she's a pretty freaking cool mom, and her sweet birthday post for her oldest son Deacon's 16th birthday is too cute! "Happy 16th Birthday to this guy, whose bright smile makes every day better!" Reese captioned her Instagram post on Wednesday. "Kind, compassionate, hysterical, friendly, and talented . . . I'm so lucky to have a son like you!"

The supersweet caption was paired with a gorgeous photo of Reese and Deacon posing outside their home and looking altogether adorable. It's hard to believe that Deacon — aka Reese's tutor in all things TikTok — is already 16, considering that she and all of her kids could pretty much pass as twins — even her youngest son Tennessee, who just turned 7. Here's to hoping Deacon has a very happy 16th birthday and that Reese sneaks in a few more family filled TikTok videos soon.
