Celebrity endorsement is a marketing and communication strategy involving the association of a renowned public figure with a product, service, or brand for promotional purposes. As an academic concept, it represents a substantial area of inquiry within marketing, consumer behavior, and communication studies, investigating the psychological and social processes through which celebrity attributes influence consumer attitudes, perceptions, and purchasing decisions, examining factors such as source credibility, attractiveness, meaning transfer, and the strategic efficacy and potential risks of such alliances.
