The Shocking Engagement: Young Thug and Mariah the Scientist
The biggest news in Young Thug’s personal life is his recent engagement to the talented singer, Mariah the Scientist. This development confirms that the "Young Thug wife" title is currently vacant, but the "fiancée" role has a new, prominent occupant.
The proposal itself was a grand, public affair. Young Thug popped the question to Mariah the Scientist onstage during his "Hometown Hero: Young Thug & Friends - A Benefit Concert" in Atlanta on December 16, 2025. This very public display of affection cemented their relationship status for the world.
Their relationship has garnered significant attention, not only because of their respective careers but also due to the circumstances of Young Thug's legal battles. Mariah the Scientist has been an incredibly supportive partner, maintaining their bond and connection even while the rapper has been incarcerated awaiting trial. Her commitment during the YSL RICO trial speaks volumes about the depth of their relationship.
The couple was first seen together publicly in late 2021, and their connection quickly became a popular topic on social media and in hip-hop circles. Despite the intense scrutiny and the legal challenges Thug faces, they have chosen to move forward with their plans to marry, signifying a new chapter for the YSL founder.
The History: Jerrika Karlae and the End of a Long-Term Engagement
Before Mariah the Scientist, the woman most associated with the "Young Thug wife" narrative was Jerrika Karlae. Their relationship was a staple of the hip-hop gossip circuit for years, marked by luxury, drama, and public declarations of love.
Jerrika Karlae is a successful entrepreneur and a rapper in her own right. She is the founder of the popular swimwear brand, Karlae Swimwear, showcasing her business acumen beyond her association with Young Thug. Her career also includes music, having signed to 300 Entertainment and collaborating with Thug on tracks like "Jimmy Choo."
The two were engaged for an extended period, leading many to believe she would eventually become Mrs. Williams. However, their relationship was volatile, reportedly ending for good around December 2020. Karlae herself publicly confirmed the split, indicating that she was moving on.
Despite the breakup, Karlae has shown support for her ex-fiancé during his current legal situation, demonstrating a level of maturity and continued care for the rapper. She has provided updates on his spirits, indicating that while their romantic relationship is over, a mutual respect remains.
Young Thug's Extensive Family and Six Children
While his romantic life has been a revolving door of public scrutiny, one constant in Jeffery Williams' life is his role as a father. Young Thug has six children—three sons and three daughters—with different women.
The rapper is known for keeping his family life relatively private, especially concerning the mothers of his children and the children themselves. However, he has shared proud father moments, such as celebrating a son's elementary school graduation. This dedication to his children, despite his demanding career and legal challenges, highlights a softer side of the YSL CEO.
The presence of his children is a significant factor in his life, and his partners, including Mariah the Scientist, must integrate into this large, complex family dynamic. The focus remains on his current legal battle and the eventual wedding to Mariah the Scientist, but the foundation of his personal world is built around his six children and the mothers who co-parent with him.
