Michael Jackson's dad, Joe Jackson, is going to the Cannes Film Festival next month to hawk a fragrance bearing the Jackson name, Breaking Celebrity News has learned.

What's more, the singing family's patriarch will also be selling Jackson champagne and vodka at the event -- this, as the involuntary manslaughter trial of the man accused of killing his son, Dr. Conrad Murray, will be under way.
