"Doin It" is a song by American rapper LL Cool J, released by Def Jam Recordings on February 20, 1995, as the second single from his sixth album, Mr. Smith.

Based on a sample of Grace Jones' "My Jamaican Guy", it contains a guest appearance from LeShaun (who previously released a song with the same sample and theme in 1988 titled "Wild Thang"), while production was handled by Rashad "Ringo" Smith and LL Cool J.

In several interviews, both the artist and producer have stated that the instrumental was originally meant for the Notorious B.I.G.

[2][3] The remix featured on the soundtrack to The Nutty Professor samples the Art of Noise's song "Moments in Love."

[4] LeShaun did not appear in the music video, as she was pregnant at the time, although several models took her place and lip synced her parts.
