Twitter Makes Hailee Steinfeld's Barden Bella Status Official! 

We all know nothing is really official until it's on social media, so when we heard Hailee Steinfeld joined the cast of Pitch Perfect 2, we kept searching the many Instagram and Twitter set pics the cast has been posting for a glimpse of the star.  Hailee finally made her Barden Bella debut this weekend, when Rebel Wilson tweeted out this adorable snap of the Bella's rehearsal.
