<![CDATA[The advancement of technology and information has driven the emergence of consumptive behavior in society, including among fans of the idol group JKT48. One of the factors that may influence such behavior is celebrity worship, which refers to an individual's emotional attachment to a celebrity. The MarshaOshi community, as part of the JKT48 fanbase, shows strong indications of high consumptive behavior. This study aims to examine the relationship between celebrity worship and consumptive behavior within the MarshaOshi community. A quantitative correlational approach was employed with a convenience sampling technique. The sample consisted of 116 members of the MarshaOshi community, selected based on their active involvement with Marsha JKT48. The research instrument used a four-point Likert scale developed based on the aspects of celebrity worship. Data were analyzed using Spearman correlation with the assistance of SPSS 27.0. The results revealed a positive and significant relationship between celebrity worship and consumptive behavior (r = 0,938 ; p = 0,00). The higher the level of celebrity worship, the greater the tendency toward consumptive behavior. These findings are expected to serve as a foundation for educating fans to support their idols wisely without placing a burden on their personal finances.
