*50 Cent is very upset right now and has threatened to do some irrational things.

The rapper, who has long delayed his fifth album, “Black Magic,” is in search of a label.

After confirming a release date in November 2011, it looks like he won’t be making that deadline. In a Twitter rant he bad-mouthed his label, Interscope, adding he’s not going to release the album.

Man I’m not releasing a album i can’t believe Interscope is this f—ed up right now. I apologize to all my fans,” he wrote. “They dropped the ball with me one time to many.”

In his frustration, he claims to have leaked a single “I’m On It” and also threatened to leak Dr. Dre’s new single, “Psycho.”

I LOVE DRE but I’m putting his next single psycho out tomorrow at 2:00″ the frustrated rapper continued. “Your [sic] gonna love it its a big song I just don’t think it deserves a great set up sense [sic] they can’t seem to get it right when it comes to me.”

Then he changed his mind after calming down a bit. And came back with a more reasonable rant.

I wouldn’t leak dre’s record he has done nothing but help me in my career. jimmy has always been supportive of me,” 50 conceded, before urging fans to check out his leaked single. “I hate when I can’t present my music the way I feel it should be but f— it check out I’m ON IT.”
