The actress refused to go into details and wouldn't confirm or deny if the project was another "Pitch Perfect", but she told U.S. talk show host Ellen DeGeneres she and her castmates "always wanna work together".
The Australian star, who was a guest on Ellen's Halloween show on Wednesday, October 31, said, "I'll definitely be filming another musical film in the next 12 months, I can say that."
She then added, "Us 'Pitch Perfect' girls, we love each other and we always wanna work together."
In the snap, she, birthday girl Anna, Brittany Snow, and Chrissie Fit hold up four fingers, which led many fans to believe they were announcing "Pitch Perfect 4".
"Pitch Perfect 3" hit cinemas last year (17).
