He fell in love with it at the age of nine, and by 11 he was writing lyrics and making his own songs with some DJ equipment his grandmother gave him to stop him riding motorcycles or doing karate. Before too long, LL was an established member of the Hip-Hop community in his area. He gained notoriety through his many rap battles against well-established MCs, including the battle against Chicken and Porn that rocketed him to fame.

He is known for co-writing chart topping hits such as "Baby" for Justin Bieber, "Umbrella" for Rihanna and "Single Ladies (Put a Ring on It)" for Beyoncé, as well as for his three solo albums, Love Hate, Love vs. Money, and Love King.

His mother died in 1992 when Nash was fifteen years old, an event which would inspire him to write songs. He states that the death of his mother gave him a "soft spot" for women, which he credits to his desire to write songs about female empowerment such as Rihanna's "Umbrella". He moved in with his grandfather, a concrete mason who instilled a strong work ethic in young Nash. Of his grandfather, Nash recalls "He came out of a bad time for blacks in the South, but even though we lived in the hood, we had a boat, some cars and a house that was paid for. So I’ve always had a different outlook on life. There’s nothing I can’t do."
