Unsurprisingly, we weren't the only ones to wish "The Hunger Games" starlet Jennifer Lawrence a happy birthday today. And perhaps the most adorable message came from her on-screen sis, Willow Shields, who plays Prim in the film franchise.
Happy Birthday to Jennifer Lawrence! Best on screen big sister ever!— Willow Shields (@WillowShields) August 15, 2013
We can't help but wonder now how District 12 is planning to celebrate...
Leave your birthday wishes for JLaw in the comments!
