Cheers to Reese Witherspoon and Her Awesome 12-Year-Old Son!

The Academy Award winner wanted to make sure that absolutely everyone knows how gorgeous her son Deacon looks on his 12th birthday, so no sooner had the party started, than she already uploaded this fancy snap to Instagram, captioning it "Happy birthday to my sweet 12 year old boy! You bring joy to everyone you know. I feel so blessed to be your mom ❤️".

Like it or not, you've got to hand it to Deacon - he does look dapper in a suit and bow tie and he also seems to be sending lots of positive vibes with that charming smile of his. Actually, it sort of comes as no surprise, considering that he is, after all, Reese Witherspoon and Ryan Phillippe's son.

Now, if you're prepared for a cuteness overload, check out this pic, which features not only Deacon, but also his 3-year old bro Tennessee James. Yay!

Is it just us or Reese's boys look exceedingly handsome in bow ties? "These two... ❤️❤️❤️#BrotherlyLove" is the caption the Legally Blonde star used for this photo, and we couldn't agree more.

Anyway, we wish you a very Happy Birthday, Deacon. Stay awesome and show your baby brother what being a gentleman is all about!

EXTRA: Here's what Deacon's birthday cake looked like. Way to go, golf lover!
