Dupri, who did not attend Michael Jackson's memorial last week, produced songs on Jackson's last two albums, which may have been a factor in the break-up, according to the source. "You shouldn't mix business with pleasure," the friend says. "Janet felt their lives were too crossed and they should have kept things sepa­rate."Jackson, who's keeping busy looking after Michael's children, an insider says, was previously (and secretly) married to Rene Elizondo. They divorced in 2000.
