T-Pain leaked a new song to the internet this week, in which he apologizes to Jay-Z for publicly dissing him last month during a performance in Las Vegas.

In the new track, where Pain croons over Drake's "Successful" intrumental," the singer blames the alcohol for saying "F*** Jay-Z."

"So that Nuvo got me poppin' sh**," Pain starts things off with. "All right, so let's talk about this Jay sh** / Somedays I wish that I ain't never say sh** / And Diddy said ain't no excuse for what I did / But I felt like he was knocking the same sh** that feeds my kids / I do music 'cause I need it to make my world spin / So when you down it, it's like you dissing my girlfriend."

Then later, as Pain continues to plead his case, he says that all Jay had to do to put him at ease -- after dropping the damaging "D.O.A. (Death of Auto-Tune)" track -- is tell the world that he and T-Pain "were cool."

In the end, the singer says it's "his bad" for dissing him.

"If you really feel like I'm dead, then n**** me too / I ain't tryna write your rhymes / But you coulda skipped one DJ and all you had to say was 'T-Pain, we cool'," Pain says in the song. "But by all means don't take this as a diss or hatin' / I just wanna explain my side of the situation / So if you knew just how much respect I had / You'd know that I'm a real n**** when I say, 'My bad.'"

During a performance in Las Vegas in early September, T-Pain was caught on camera dissing Jay after a fan in the crowd yelled out "Jay-Z destroyed you."

The comment pissed him off so bad that he took aim at Jay, saying "f*** Jay", as well as calling him old.

Not only did fans catch the diss on camera, but rapper Fabolous was also in attendence, and tweeted about it. Then, later dissed T-Pain for it.

In a radio interview a few days later, T-Pain explained his frustration with the "D.O.A." song, and his disappointment with Jay never publicly saying it wasn't a diss toward him.

He said he was sorry, and said there was no beef between he and Jay-Z, and/or Fabolous.
