I saw her on her last tour (may of 04 in Vegas). I wish I could go this year, espically since she is performing in Phoenix(only a few hour drive for me). She is an amazing performer.
The range for her tickets is $55 -$350. For $55 you probably can't even see the jumbotron. I would to see her. I've been a fan since the beginning. For three yrs I dressed up as Madonna for Haloween when I was little. Jelly bracelets and all!
