Madonna [ tickets ]'s Los Angeles-area fans snapped up tickets for the singer's May 21 tour kick-off in a hurry, leading organizers to roll out a second date.

Shows are now set for May 21 and May 23, tickets for both of which are on sale now. The new LA-area date follows Friday's (4/7) addition of second nights in Chicago and Fresno, CA.

Tickets for a number of other shows are scheduled to go on sale Monday (4/10). Details are included in the itinerary below.

Madonna is gearing up for a world tour behind last year's "Confessions on a Dance Floor." Jamie King, one of the singer's longtime collaborators, will direct the "Confessions Tour," and Stuart Price will again be on board as musical director, according to a press release.

Arianne Phillips and Jean Paul Gaultier, long-standing members of Madonna's creative team, will respectively oversee and design costumes for the tour.

Following her tour's North American leg, Madonna heads across the pond for a European trek, details about which are posted at the tour's official website. Tickets for the Euro leg went on sale this past weekend, and sold out in 10 minutes, according to information posted at Madonna's website.

As previously reported, Madonna will warm up for her headlining trek with an April 30 set at this year's Coachella Valley Music & Arts Festival.

Released last November, "Confessions on a Dance Floor" debuted at No. 1 on The Billboard 200 and has sold more than 1.3 million copies in the US to date, according to Warner Bros. Records. Sales have been fueled in part by the hit single "Sorry."
