Pop’s greatest showgirl is preparing to kick off her latest world tour on Saturday with a gig at the Cardiff Millennium Stadium in Wales.

The Sticky and Sweet World show is set to tour Europe, with a stop at Wembley stadium on Sept. 11, before heading to the U.S. and South America later in the autumn.

The Queen of Pop, who has just turned 50, will be promoting her album "Hard Candy," which features a duet with American heart-throb Justin Timberlake.

Her reputation for incredible live performances is expected to pull the crowds with a show that features 16 dancers, a 12-piece band, more than eight costume changes for Madonna alone and $1.8 million of Swarovski crystals.

The show will be divided into four parts: Pimp, an homage to 1920s deco and modern gangsta pimp; Old School, a throwback to Madonna’s 1980s New York roots; Gypsy, drawing on La Isla Bonita and a Romani vibe; and Rave, with allusions to the Far East.

Other European dates will include Nice, Berlin, Amsterdam, Dusseldorf, Rome, Franfurt and Paris.
