Jamie, 23, is promoting Massapo, a bissap brand he created with his brothers, by traveling through Paris and offering free samples to celebrities. Bissap is a traditional Senegalese drink made from hibiscus flowers, often served cold and sweetened. Jamie has met several well-known personalities, including footballer Mamadou Sakho, artist Kalash, and fashion designer Mike Amiri. However, Christian Louboutin, the renowned shoe designer, is said to have provided the most support by connecting Jamie with others and inviting him to exclusive events. During one of Jamie's encounters, Celine Dion improvised a song titled "Massapo je l'ai dans la peau" ("Massapo is in my skin") in front of her hotel, giving the brand free publicity. Though the song was not an official release, it was a spontaneous tribute to Jamie's family business. The moment was significant for the brand, as it brought attention to Massapo in a unique and memorable way. Jamie and his brothers started Massapo to sell bissap, a drink with roots in West African culture. Jamie handles the brand's social media promotion, and his TikTok account has grown to more than 39,000 followers who track his daily journey through Paris as he seeks out celebrities. His goal is to give each star a bottle of Massapo and film their reactions. He calls himself a "friend of the stars" and credits his background in the hospitality and restaurant industry for helping him overcome shyness and approach people confidently. Four celebrities have tried Massapo and offered Jamie feedback: Mamadou Sakho, Kalash, Mike Amiri, and Christian Louboutin. Jamie recalls that Celine Dion initially told him he was speaking too quickly but later created a song for him, now recognizing his efforts. Despite some fans doubting that Celine Dion would acknowledge him, Jamie chose to focus on his mission. As Paris Fashion Week approaches, Jamie is actively promoting Massapo, ready to sing the song in honor of his brand.
