The Queen of Pop is ready to embark on another spectacular world tour, this time in support of her chart-topping album “Hard Candy.” The provocatively titled “Sweet and Sticky” tour kicks off Aug. 23 in Cardiff, Wales.

Madonna is never one to idle and her summer plans go to show. Her “Sweet and Sticky” world tour begins shortly after she celebrates her 50th anniversary on August 16, the pop star announced Wednesday.

A press release posted on her website on May 8 promises that Madonna, “the world’s tastiest sweetheart,” has more “more non-stop treats for her legions of legendary and devoted fans.”

Her tour will debut August 23 in Cardiff, Wales, and continue through Europe, making stops in France, Germany, the Netherlands, Italy and the U.K., including a Sept. 11 performance at London’s Wembley Stadium.

The North American leg begins October 3 at the Izod Center in East Rutherford, New Jersey, with stops at New York’s Madison Square Garden on October 6 and 7, followed by performances in Boston, Chicago, Los Angeles. The last U. S. date is on Nov. 26 at Miami’s Dolphin Stadium.

Madonna will also regale fans in Mexico and South America later this year, with show dates to be released.

Tickets for “Sticky & Sweet” go on sale Friday, May 16 in London, Paris, Cardiff and Nice followed by on sales Saturday, May 17 in Amsterdam, Boston and Chicago with E. Rutherford and New York City on sale Monday, May 19, her website says.

This is the fourth worldwide tour produced by Live Nation. Her last tour, 2006’s “Confessions,” was hugely successful and has become the highest grossing concert tour of all time by a female artist.

“Hard Candy” is Madonna’s eleventh and final album for Warner Bros. It has debuted at No. 1 among the world. Her first single off the album, a duet with Justin Timberlake titled “4 Minutes,” secured the star the title of artist with most top-ten singles in the modern pop era - 37, a title previously held by Elvis Presley.

Last year, Live Nation signed a previously unheard-of deal with Madonna. The concert promoter and the Queen of Pop reportedly signed a 10-year, $120 million contract in October, under which Madonna would receive cash and stock and give Live Nation exclusive rights to sell three studio albums, promote concert tours, sell her merchandise and license her name.
