Floyd Mayweather’s grandson is officially five, and the milestone was marked with a low-key, family-centered celebration led by his daughter, Yaya Mayweather.
Over the weekend, Yaya shared glimpses of how she celebrated her son Kentrell Jr.’s birthday, opting for a simple, hands-on moment at home rather than an extravagant party. According to the posts, the birthday boy made a specific request: he wanted to bake his own cake. Yaya happily obliged, documenting the late-night kitchen session that turned into the centerpiece of the celebration.

One clip showed a mother and son cracking eggs and mixing the batter, while another captured KJ smiling as family members gathered around to sing “Happy Birthday.” The cake itself was rectangular and decorated with white and light red frosting, and KJ capped off the moment by blowing out a single candle while wearing a Spider-Man T-shirt. The visuals reflected an intimate celebration focused on time together rather than spectacle.
While Yaya handled birthday duties at home, the occasion was also marked by loving messages from across the Mayweather family. KJ’s grandmother, Melissa, shared a heartfelt tribute on Instagram, along with studio photos of her grandson, calling him “the biggest and best blessing to our family” and noting the joy he has brought to their lives since birth. She added that she knew from the moment she met him that he would be “somebody very special.”
