Grammy-winning superstar **Billie Eilish** is celebrating her 20th trip around the sun - and her big brother is marking the occasion with *the sweetest* message ever!

Taking to Insta, **Finneas O'Connell,** who's four years older than Billie and also happens to be a Grammy-winner (*what a family, hey!*), writes: "20!!!!!!! Watching you grow and become the thoughtful, incredibly kind, talented, hilarious and hardworking person that you are today has been the joy of my life!"

He adds: "I'll be your #1 fan till the day that I die. There is truly nothing I love more than being your big brother. Happy birthday!!!"

Finneas also shared two pics of Billie sitting on a wooden floor with a pastel green top on as well as a clip of her jokingly "eating" their mother's hair!

Speaking of Billie's mama, she shared an equally heart-melting message on her own Insta page along with a series of throwbacks of Billie as a little girl.

"Happy Birthday Billie Eilish Pirate Baird O'Connell!!" she captioned the *seriously adorable* pics.

"You are funny, and complicated, and goofy, and tough, and strong, and brilliant! Your joy for the holidays and things birthday and Christmas, gifts so much joy to our family. How can someone be so powerful and so goofy and childlike at the same time? I don't know, but you make like more exciting and tender. I love you with ALL my heart and soul."

What. A. Family.
