Floyd Mayweather may have boxed his way to victory and an estimated $375 million from his fight with Conor McGregor, but it wasn't all fun and games for one of the greatest boxers of all time.
Now on his way to the billionaire's club, Floyd, who uses the nickname "Money", has a rags to riches story after being raised in poverty by a dysfunctional family.
Living in a New Jersey apartment sharing a bedroom with six kids, Mayweather would often come home from school to find heroin needles in the front garden and would go for days or weeks with no electricity.
His father was jailed for drug dealing while his mother was a drug addict.
In a previous interview, Mayweather claimed: "I was the man in the house from 16. That's just the way it was."
