The album is due to drop April 30, the record company said.
The performance is now available on iTunes and the song will be featured on LL Cool J's new album.
"With 'Authentic,' I wanted to work on a project that was for the true fans," the singer said in a statement. "I'm not trying to compete with 17-year-olds on the radio, but I am talking directly to the folks who came up with me. We may not be teenagers anymore, but we do still like to have fun."
