Blood is thicker than water, unless it's a birthday!

It turns out actor Ryan Reynolds doesn't save birthday snark for just his wife and kids. Reynolds just sent a little birthday love to his big brother Jeff, and we're loving the sweet and salty trolling.

The Deadpool star took to Twitter to wax sentimental on his brother's special day:

I mean, come ON with that picture!

No news yet on brother Jeff's reaction, but Twitter couldn't get enough.

People couldn't help but notice the shirts:

Anyone can tweet out a generic "Happy Birthday!" But Reynolds has skills.

 Reynolds should be in charge of Twitter birthdays for everyone.

Apparently Reynolds ribbing his brother is becoming something of a family tradition. 

Last year he took a birthday swipe at his big bro that was adorable and similarly snarky.

Who's counting the minutes to Jeff's 2018 birthday?!
