While you might remember Hilary Duff as the adorable childhood actress who stole Disney’s spotlight, Lizzie McGuire is no more. The 28-year-old is all grown up with a son of her own, but that doesn’t mean she’s done with her adolescent days.
Sharing that Haylie has “always been my guiding light, my safety, my pit bull and my best friend,” Duff provided the perfect caption to an already adorable throwback.
“Your love and protection is endless! Happy birthday I love you so much,” she wrote, following up with the hashtag “ThickAsThieves.”
The sisters have always been close, but it seems they’re especially connected since Haylie gave birth to daughter Ryan Rosenberg in May ’15, providing Hilary’s son Luca with a cousin.
A very happy 31st birthday to Haylie!
