It is estimated that the fight will earn him big bucks.
But in a recent interview with the Mirror, Joshua revealed that despite now being a multi-million pound fighter, he remains as down to earth as ever.
But after he finally made the move to pro, his first instincts were to splash the cash on the people closest to him.
One of the first things he bought was his mum's council flat in Golders Green, North London, where he still lives with his social worker mother - despite having bought a £500,000 penthouse in nearby Finchley for Nicole Osbourne, the mother of his one-year-old son, Joseph.
After searching his Mercedes, police found cannabis in his kitbag and he was charged him with possession.
