Who Is Kentrell Gaulden Jr.?
Kentrell Gaulden Jr. is the son of two highly recognizable public figures — chart-topping rapper NBA YoungBoy and Iyanna “Yaya” Mayweather, the second-eldest daughter of five-division boxing world champion Floyd Mayweather Jr. Born on January 9, 2021, he is the seventh of NBA YoungBoy’s 13 publicly known children.
What makes Kentrell Jr. stand out within the Gaulden family is his dual celebrity lineage: through his father, he is part of one of hip-hop’s most influential dynasties, and through his mother, he is the grandson of one of boxing’s greatest champions. As such, he has been in the public eye since birth.
The Story Behind His Name
Kentrell Jr. is named directly after his father, Kentrell DeSean Gaulden, whose stage name is NBA YoungBoy. By giving his son the suffix “Jr.,” NBA YoungBoy publicly honored him as a namesake — a tradition that has made Kentrell Jr. one of the most distinctive names within the rapper’s family of 13 children.
Kentrell Gaulden Jr.’s Birthday and Age
Kentrell Jr. was born on January 9, 2021, making him a Capricorn. As of June 2026, he is 5 years old and will turn 6 in January 2027. His most recent birthday — his fifth — was celebrated in early January 2026 with a basketball-themed party attended by both his mother Yaya and his grandfather Floyd Mayweather Jr.
Interestingly, he shares his exact birthday — January 9 — with his half-brother Kaell Gaulden, who was born a year later on January 9, 2022.
Kentrell Jr.’s Mother — Iyanna “Yaya” Mayweather
Kentrell Jr.’s mother is Iyanna Mayweather (born May 20, 2000), commonly known by her nickname “Yaya” or “Money Yaya.” Yaya is the daughter of Floyd Mayweather Jr. and actress Melissa Brim, and the second of five Mayweather siblings.
Yaya began her relationship with NBA YoungBoy in 2018, and although the couple briefly got engaged in 2020, they never married and their relationship has been on-and-off in the years since. As of 2026, they are no longer together, though Yaya has publicly maintained warm support for NBA YoungBoy, posting on Instagram: “I love you more than words could ever explain, and no matter how far away you go in the world, I’ll always be here for you, cheering you on.”
Yaya is Kentrell Jr.’s only child, and she focuses much of her public presence on motherhood. In August 2025, she publicly denied rumors that she was expecting a second child with NBA YoungBoy.
Kentrell Jr.’s Father — NBA YoungBoy
Kentrell Jr.’s father is American rapper NBA YoungBoy, real name Kentrell DeSean Gaulden, born October 20, 1999, in Baton Rouge, Louisiana. NBA YoungBoy is one of the most streamed rappers of his generation and the founder of independent label Never Broke Again, LLC.
NBA YoungBoy is publicly known to be the father of 13 children, with Kentrell Jr. being one of his namesake sons. He has remained involved in Kentrell Jr.’s life despite his split from Yaya, and in early 2026, he gifted his former father-in-law Floyd Mayweather Jr. a Lamborghini truck — widely viewed as a gesture of family goodwill.
Floyd Mayweather Jr. — The Celebrity Grandfather
One of the defining aspects of Kentrell Jr.’s life is his close bond with his maternal grandfather, Floyd Mayweather Jr. — a five-division world champion boxer widely considered one of the greatest fighters in boxing history. Floyd Mayweather has been openly devoted to his grandson since birth, regularly sharing moments with him on social media.

- Sparring sessions in Mayweather’s home gym
- Family outings to skating rinks and amusement parks
- Quiet moments of Kentrell Jr. resting on his grandfather’s lap
