It’s everyone’s favorite supermodel, Gigi Hadid ‘s 22nd birthday today, and though the golden girl (who’s singlehandedly bringing jorts back) has plenty of well wishers, including VS angel Lily Aldridge and proud momma Yolanda Hadid, it was little sis Bella’s post to her “role model” that had us all kinds of choked up.

With a slideshow of no less than 10 super sweet shots of the famous sisters together (click the arrow at the right middle of the page to see them all) at various stages in their lives, she penned an emotional tribute to Gigi to rival the one Dakota Fanning penned for Elle earlier this month.

“Happy birthday to my best friend for f**cking LIFE!!!!!!! My role model! My person. I feel lucky every day to call you my sister. I didn’t know anyone could be so generous, smart, funny, talented, hard working, artistic, loving, respectful, and beautiful all at the same d*mn time!!! You make me laugh until I pee and even when I don’t want to smile, you are just about the only person that can make me. Everyone that knows you immediately feels the incredible energy that radiates throughout you. Thank you for always being yourself, nothing more and nothing less. You are my other half and I don’t know what I would ever do without you. I love you with all of my heart Squeegee.”

Okay, we don’t know about you, but we seriously just shed a tear. How freaking sweet are these two?

It’s no surprise the pair is super close: The girls do practically everything together, from walking the runway at Victoria’s Secret to protesting for what they believe in. From the looks of the youngest Hadid’s pics, that’s the way things have always been, with Bella wrapped in Gigi’s protective arms on more than one occasion.

Happy birthday Gigi — It sounds like Bella’s a pretty lucky little sis.
