RUMORS FLY SURROUNDING DUPRI'S DEF JAM EXIT: Page Six says mogul's heart was no longer in job after girlfriend's album tanked.

      *Producer Jermaine Dupri was reportedly dropped from his position as President of Island Records Urban Music because he stopped showing up for work when his girlfriend Janet Jackson's album flopped.
     
      "After (his girlfriend) Janet Jackson's album and tour bombed, he basically didn't come back to work," a source told the New York Post. "He still collected a paycheck, but didn't bother to do anything that he was supposed to do, like find artists, release records or actually show up.
     
      "Executives tried to talk to him, but he just lost heart. Very few producers have turned into good executives, with the exception of Dr. Dre."
     
      As previously reported, Dupri's role has been "terminated effective immediately." Jackson's "Discipline" was released last February, but had only shifted an estimated 415,000 copies in the U.S. by September that year. Island Def Jam reportedly stopped promoting the album in June 2008.
