The Bellas are back, along with some new friends, in the new "Pitch Perfect 3" trailer tease, taking fans behind-the-scenes on a global tour.

The teaser follows director Trish Sie on set, along with stars Anna Kendrick, Anna Camp, Brittany Snow, Rebel Wilson, Ester Dean, Chrissie Fit, Hana Mae Lee, Hailee Steinfeld, and John Michael Higgins, along with newbies Ruby Rose, Andy Allo, DJ Khaled, and John Lithgow.

"Rebel and John are like peas in a pod," Sie says, showing footage of Wilson and Lithgow clowning around on set. Rebel Wilson argues that she's the most badass Bella, since she has to run at least 10 steps in a scene, and she has to be attacked by a dog that she's also allergic to. But you can see some actual badass action scenes, including Anna Kendrick jumping off some kind of smoking ship in a night shoot, along with other Bellas who are now "action stars."

Watch the behind-the-scenes tease:An official trailer will show up whenever it's ready, and there's plenty of time, since "Pitch Perfect 3" doesn't open until December 22.
