The Hackney-born fighter's elevation to world champion capped a great year for the Dubois name after Daniel legitimised his world-title reign with a dominant win over Anthony Joshua in September.
The siblings joined light-middleweight champion Sebastian Fundora and undisputed flyweight queen Gabriela Fundora in becoming a brother-sister world champions.
But the feat was bitter-sweet. Dubois left her family home following a rift with her father, Stan, in 2023 and has reportedly not spoken to her brother either.
Stan and his daughter have given their versions of the feud in separate interviews, and without getting too drawn into the details, the boxing champion says the sport provided solace during some "dark moments".
"I just keep reminding myself of the positives and the blessings instead of all the sadness and the negatives that come with being a human being," Dubois adds.
"How many people are going to say they wanted to do something at nine years old and be doing it at 24?
"If boxing was taken away from me tomorrow, I would be devastated. I would be broken. So you just remember that when it gets a little bit tough."
