Madonna managed to create controversy again. This time not due to sex, but politics. The 50-year-old diva kicked off her Sticky & Sweet world tour with a concert in which she expressed her political views.

During the show that took place in Millennium Stadium in Cardiff, Wales, Madonna chose to show a video which associated images of destruction and global warming, photos of Adolf Hitler and Zimbabwe’s president Robert Mugabe with Senator John McCain.

Towards the end of the video, which was played while the pop diva performed the song “Get Stupid,” the image of her favorite presidential candidate, Barack Obama, was accompanied by images of slain Beatle John Lennon, former US vice-president Al Gore and Mahatma Gandhi.

In a statement reported by Fox News, McCain campaign spokesman Tucker Bounds expressed his anger towards the fragment of Madonna’s concert that connected the Republican presidential candidate McCain with Hitler and Mugabe, saying that the comparisons were “outrageous, unacceptable and crudely divisive all at the same time.”

“It clearly shows that when it comes to supporting Barack Obama, his fellow worldwide celebrities refuse to consider any smear or attack off limits,” Bounds added.

The rest of Madonna’s show went on as usual, with hypnotizing dancing and sexy outfits, complete with fishnets and bondages. It was reported that 36 designers worked to create about 3,500 items of clothing specifically for Madonna’s tour.

A couple of weeks ago, Givenchy spokeswoman Caroline Deroche-Pasquier said that Riccardo Tisci from Givenchy created two concert outfits for Madonna’s upcoming world tour "Sticky & Sweet.”

In a press statement, Tisci himself expressed his excitement at the fact that he had the opportunity to “offer the world of Givenchy Haute Couture to Madonna the Icon, the Artist, the Woman for whom I have so much respect and admiration.”

Madonna has worked with big designers before, when organizing her tours. She collaborated with Jean-Paul Gaultier for her 1990 “Blonde Ambition” tour, and with Dolce & Gabbana in 1993.

Givenchy said that Madonna’s first outfit would be “a reference to 'Gangster Pimp' and Art Deco,” while the second would be of gypsy inspiration. And that’s no surprise, as Madonna revealed her plans of singing together with Romanian gypsies during her tour.

The singer’s “gypsy outfit” includes a long-hooded cape in black silk taffeta embroidered with jet stones and a dress with multicolored ribbons and fuchsia colored metal chains.

The queen of pop made a grand stage entrance at the Cardiff concert, appearing on a throne while she performed her popular hit “Candy Shop” in front of about 40,000 screaming fans, her husband Guy Ritchie and her children: Lourdes, Rocco and adopted son David, who all happily cheered.

The show was divided into four sections – “gangsta pimp, rave, gypsy and old school.”

Madonna is awaited in 51 more locations, among which 16 are in Europe. Then she will head to North America and end the tour in December in Sao Paulo, Brazil.

It is Madonna's first tour since striking a deal with concert promoter Live Nation worth an estimated 120 million dollars over 10 years.
