What was supposed to be an "intimate" concert for Madonna fan club members ended in public outcry after audience members gathered at the 2,700-seat Olympia Theatre in Paris became disgruntled over the singer's abrupt departure just 45-minutes into her set.

If the UK's Daily Mirror is to be believed, Madonna's MDNA tour rider includes one particularly apt request from each venue she visits: Do not enter her dressing room until after it has been scrubbed clean of her DNA.

On her 12th studio album, MDNA (out this week), Madonna sometimes talks about her life with Guy Ritchie ("Would you have married me if I were poor?"). But her self-fixation, the album's real theme, is generally career-focused. You hear it in the way the way that certain songs echo her past work — "I'm a Sinner" breaks with a guitar solo a la "Ray of Light" and sports the plastic psychedelia of "Beautiful Stranger," while the chord progression of "Beautiful Killer" is similar to that of "Die Another Day." There are overt references, too – "Like a Virgin," "Into the Groove" and "Lucky Star" are name checked. The album opens with, "Oh my God, I am heartily sorry for having offended thee and I detest all my sins..." which she previously said in Like a Prayer's "Act of Contrition."

To promote yesterday's release of her new album, Madonna joined Twitter for a single enchanting day. Using the clever album plug-handle @MadonnaMDNADay, Madonna fielded questions from fans who tweeted at her and used the augural hashtag, #AskMadonna.
