Madonna Finishes William Orbit's Sentences

While Lady Gaga, Justin Bieber and Rihanna have adopted Twitter as their forum of choice when communicating with fans, Her Madgesty has been ramping up her Facebook presence as MDNA's March 26 release nears. She's been socializing minute-long snippets of several MDNA album tracks — including "I'm Addicted" and "Gang Bang" — posting behind-the-scenes pictures of tour rehearsals and polling her fans about which back-catalog songs they'd like to hear when she hits the road.
