Hi there!
Last I heard Meat mentioned that she was going to be starring in a new HBO series. So, I would imagine she might be busy with that, instead of the tour (although HBO series often only have 7 or 8 episodes to begin with, I think. That would open the possibility of her joining the tour later in the year).
Went to the HBO website, by the way, but couldn't find out anything more about it. If anyone hears anything, please post it! Would love to know what the series is going to be like.
Hope this helps a little!
Love,
MB
