Which character in Camp Rock 3 plays the cello?

Rosie is the Camp Rock 3 character who plays the cello.

Rosie is introduced as a cellist among the new campers at Camp Rock. She joins Sage, Desi, Cliff, Fletch, and Maddie’s group in the competition to find a new opening act for Connect 3.

The film gives the campers different creative specialties. Cliff is a drummer, Callie is an aspiring dancer, and Sage is a singer and songwriter. These varied talents help the competition develop into a group performance rather than a contest limited to one type of performer.

Rosie is portrayed by Lumi Pollack. The character should not be confused with Callie, who helps lead the dance-focused second challenge, or Maddie, the popular social influencer who arrives with backup dancers. Rosie’s defining musical detail is her cello playing.
