Last week, a spy tells us, Madonna was getting ready to go onstage in Chicago when someone told her Carey had been forced to cancel three tour dates. (Billboard reports that Madge's "Confessions" tour is on track to gross a record-breaking $200 million.)
"Madonna laughed hysterically," according to a source. "She has been asking her tour promoters to E-mail her Mariah's numbers!"
Madonna is also said to have been tickled to hear that Carey didn't appreciate her musical director, "American Idol" judge Randy Jackson, revealing on TV that he'd been inspired by Madonna's show in L.A. Madonna's rep, Liz Rosenberg, argues that Madonna doesn't give a fig about Carey's ticket sales — and "she has no negative feelings toward Mariah."
