Madonna [ tickets ] will launch another round of her "Sticky & Sweet" tour this summer, an international slate that will include markets she missed on last year's version of the tour.

"This is a first for me. I've never extended a tour before," Madonna said in a press statement. "I'm excited to be going back on the road, visiting places I've never been and returning to places I love."

The singer kicks off the tour July 4 in London, the first of 16 concerts in 13 countries this summer, with the trek scheduled to run through an Aug. 20 appearance in Ljubljana, Slovenia. Details are included below. Additional ticketing information, including on-sale dates and VIP packages, can be found at Madonna's official website.

Fans can expect the same impressive stage show that the Material Girl toted around the world with her last year. According to tour promoter Live Nation, the production features "3,500 wardrobe elements, 36 clothing designers, 100 pairs of kneepads, 12 trampolines, 69 guitars, a traveling personnel of 250, five keyboards for Kevin Antunes the musical director, three members of the Russian Romani (Gypsy) group the Kolpakov Trio, 18 dancers, one set of Swavorski crystal encrusted ear phones and one Material Girl."

Madonna is still supporting her 11th studio album, "Hard Candy," which surfaced last April and debuted at No. 1 in more than 30 countries, including the US. Her latest single, "Miles Away," gave the performer her seventh consecutive No. 1 single on Billboard's Hot Dance Airplay chart, making her the only artist to achieve the feat.

Madonna's previous album, 2005's "Confessions on a Dance Floor," sold more than 8.5 million copies, and her 2006 outing to support the set became the highest-grossing concert tour of all time by a female artist, a figure surpassed by last year's "Sticky & Sweet" tour, which pulled in $280 million in ticket sales worldwide, according to a press release.

Additionally, the North American portion of the trek was the highest-grossing tour on the continent last year, racking up a total of $105.3 million in ticket sales, according to concert-industry trade-magazine Pollstar.
