One Tree Hill star leaves the loveliest of lovely birthday message for co-star

Ah, One Tree Hill. The noughties show that outlasted them all, running for an impressive nine seasons and taking those teens well past their high school days and into adulthood.

One of the central friendships on the show was, of course, Brooke and Peyton, as turbulent as it could be at times, and as much as that Lucas Scott tried to get in the way.

Fans of the show will be happy to know that 'Breyton' are very much still friends in real life, with Sophia Bush dropping Hilarie Burton a very sweet birthday message on Instagram the other day.

Happiest Birthday to my sweet @hilarieburton. Sister! We've been through a lot. At least 374 hair colors together. Crushes. Heartbreaks. Hangovers. Halloweens. Tears and laughter. Fear and joy. Successes and burn-it-to-the-ground failures. We've fought like rams and loved like family. It's such a thrill to be in this place with you, 14 years after we first met and danced too late in bars -- still giddy that we were finally 21 -- and to watch you shine. You're a champion for your community. An incredible mom. You're the alpaca whisperer. You're whip smart and razor sharp and deeply tender. There is no one I would have rather been on the world's most insane roller coaster with. And I'm so glad there's evidence that we both used to overpluck our eyebrows, undeniably, on the internet forever. At least we're not alone. I love you mama. #Breyton4eva #BreytonFeels #ShesMine #BetterInRealLife

N'awww. And no doubt there are many who can relate to that over-plucking the eyebrows remark.

Now, when is the inevitable reunion show going to happen?
