I chatted about this on the show Monday evening. In the latest issue of Rolling Stone, the magazine compares Madonna’s upcoming world tour to Lady GaGa’s forthcoming “Born This Way Ball.” The figures are staggering, and I think they paint a very clear picture as to who the bigger pop star is, and how much space is between the two.

Bottom line: Madge will perform half the shows and bring in double the money. Game, set, match… for now.
