The Hollywood Reporter said Janet's managers wrote a clause into the contract for the "Number Ones, Up Close and Personal" world tour that specifies Jackson jokes are off limits for any comedians who warm up the crowd.
The contract states "that comedian[s] will not make any reference to Janet Jackson or the Jackson family," the entertainment trade newspaper said.
The contract also requires some backstage specifics such as red scented candles and two cases of Miller High Life beer.
As for the more serious parts of the deal, Jackson will bank a minimum of $450,000 per show with an additional 85 percent of gross box-office receipts greater than $650,000. She also will be reimbursed $25,000 for the use of her personal sound equipment, the Reporter said.
