Alexis Knapp - More Bella love. Anna & Brittany couldn't make it in this one b/c they were busy making out. #pp2 What's the best part about the return of "Pitch Perfect"? For Alexis Knapp, it has to be spending some quality time with these gals. She shared this behind-the-scenes shot from the set of "Pitch Perfect 2," along with co-stars Rebel Wilson, Hailee Steinfeld, Hana Mae Lee, and Ester Dean. Looks like fun, ladies!
