Purpose: The purpose of this study is to investigate the effect of celebrity endorsement components (expertise, attractiveness, and trustworthiness) on brand attitude, brand loyalty, and purchase intention. This study looks at the elements of celebrity endorsements that influence young consumers' purchasing preferences in the Barishal region of Bangladesh. Methodology: The study model incorporates constructs from earlier literature that have been proven to have substantial relations with purchasing intention. A self-administered questionnaire has been used through an online survey to collect 205 data from young people aged 20 to 24. Additionally, SPSS has been used to analyze the data. Findings: The study demonstrates that celebrity expertise and trustworthiness significantly influence brand attitudes and brand loyalty. However, celebrity attractiveness is not much impacted by brand attitudes and brand loyalty. The study also demonstrates that brand loyalty is the most substantial influence on purchase intention. Practical Implications: The findings of this study will help producers, marketers, merchants, and advertisers figure out what traits of a celebrity contribute to a favorable brand attitude, brand loyalty, and buy intention. Originality: This paper empirically examines how different variables affect celebrity endorsement’s influence on the buying behaviour of consumers’ decisions of young customers. Research Limitations: In this study, the respondents are young, so the findings may not be applicable on a general basis.
