the only reason shes adding south american dates its because her tour doesnt have enough USA dates,why since her first tour she never tought about going to south america or Mexico?(last date added) thats what American singers do when they don´t have a strong tour thats profitable ,they start to visit countries they never tought about as if they do some big favor to their fans ,they just try to milk the cow till the last drop.she should learn from katy p or lady g(im not a fan of them ,don´t like their music),they have been visiting those countries since the start of their carrers because they really care about their fans in those places ,but miss b its just doing it because her last cd was a comercial failure and shes not selling dates like before .. a real shame!
