IS JA RULE FED UP WITH IRV GOTTI?: Rapper reportedly upset that his album 'The Mirror' hasn't left the wall.

The Inc founder Irv Gotti and his star artist Ja Rule are rumored to be bickering over the rapper's new album "The Mirror" because its release date keeps getting pushed back.

"Irv tried to release two singles - 'Uh-Oh' and 'Body' - and they got no radio play, so he got nervous," a source tells the New York Post's Page Six. "The album was supposed to come out Sept. 18 and was pushed back to Nov. 13 and now has no date except 2008. Irv wants Ja to record over the holidays and Ja feels he's done enough. He's furious."

A rep for Ja, however, denies that her client and Irv are fighting, stating: "That's not true. They get along very well. They're brothers."

She said "The Mirror" will "likely come out in February. Ja's going back in the studio to do a couple more tracks. It was a mutual decision."
