The material girl will be using the account @MadonnaMDNAday again and will be using the hashtag of #askmadonna to answer your most pressing queries. Hopefully someone here may ask her about her tour plans for Australia.
The Twitter chat will also be streamed live on her website (click THIS LINK) to see it for yourself.
The live chat kicks off at 10pm American EST, meaning midday on the Australian eastern seaboard, 11:30am central time, and 10am in Perth.
