Alyson Stoner reflected on their Camp Rock days in a newly released memoir - and spoke candidly about some highs and lows with former costar Demi Lovato. In Stoner's book, Semi-Well-Adjusted Despite Literally Everything, they recalled becoming fast friends with Lovato, 32, at a Camp Rock audition where they read for the roles of Caitlyn and Mitchie. "I oriented to Caitlyn's character profile, quickly memorizing lines and analyzing the beats of the scene," Stoner wrote in the book, which hit shelves on Tuesday, August 12.
