first of all, this has been posted before.
and secondly, if you really think this will make her fans hate her more or something like that, you're wrong.
it's all based on the gossip of a student who happened to be there (or so he claimed) on Facebook, later someone reposted it on Facebook and that's how the boss of the theatre found out. he later said he banned her for a joke on twitter. when it got more attention, he said "ok, let's ban her for real". but he's actually a fan.
this is all just a bad joke and the media running with it to try, once again, to dimnish her and make her some kind of bad person. they hate the fact that she's successful and happy, never had a breakdown, so they have to put her down themselves. and they do it by sharing complete banal nonsense you and I could be guilty of
they tried it with hydrangeas, and now they try it again: without any form of proof at all
in other words:
desperate.
and once again, it shows just how relevant she is. popgirls don't get this kind of media attention from their records. the boss of the threatre in texas is probably laughing about this with madonna herself.
