The 'Roar' hitmaker told Entrevue magazine that when she was 15, she fell in love with her friend and she thought she was beautiful and wanted to be like her, the Mirror reported.
Perry said that her friend had a huge impact on her life, but the 29-year-old singer could never express how she felt.
She added that she has told her boyfriend, John Mayer, that she would ditch him if Scarlett Johansson ever wanted to go out with her.
