James Todd Smith, better known as LL Cool J (acronym for Ladies Love Cool James), is an American rapper, songwriter, record producer, and actor. He is one of the earliest rappers to achieve commercial success, alongside fellow new school hip hop acts Beastie Boys and Run-DMC.

Signed to Def Jam Recordings in 1984, his breakthrough came with his single “I Need a Beat” and his landmark debut album, Radio (1985). He achieved further commercial and critical success with the albums Bigger and Deffer (1987), Walking with a Panther (1989), Mama Said Knock You Out (1990), Mr. Smith (1995), and Phenomenon (1997). His twelfth album, Exit 13 (2008), was his last in his long-tenured deal with Def Jam.

A two-time Grammy Award winner, LL Cool J is known for hip hop songs such as “Going Back to Cali”, “I’m Bad”, “The Boomin’ System”, “Rock the Bells”, and “Mama Said Knock You Out”, as well as R&B hits such as “Doin’ It”, “I Need Love”, “Around the Way Girl” and “Hey Lover”.
