Barden Bella's Threw Hailey Steinfeld A Surprise 21st Party

Do you ever watch a movie and wonder if the cast are friends in real life too rather than just on screen?

Well, it turns out that the cast of Pitch Perfect are friends IRL! In fact, Ruby Rose and Rebel Wilson went to great lengths to prove their friendship by throwing a surprise 21st birthday party for their co-star Hailee Steinfield. 

Rebel took to Instagram to share a video from the surprise party with the caption, “Happy 21st @haileesteinfield !! SURPRISE !! @rubyrose & I were stealth in our mission x”

From the looks of Hailee’s reaction, it appears she was totally clueless about the entire event!

The party was held at The Nice Guy in Hollywood and was attended by tons of famous faces. Celebs such as Julia Michaels, Kaitlyn Dever, Lele Pons, Alex Lange and Darren Criss were among some of those that attended the party. 

I feel like it was just a few months ago I sang at this one’s sweet sixteenth... (yeah, that happened)... happy 21st, dear sweet @haileesteinfeld
