Xtina to Strip, Whip and Flip!

TMZ has exclusively obtained documents that outline every dirrty nuance of Christina Aguilera's upcoming Back to Basics Tour.

The risque chanteuse's 22-song set is broken into three sections; 1920s, Juke Joint and Circus, and includes over 15 scantily clad costumes.

Christina will be featured in various scenarios, from a good girl gospel choir, to a sultry strip tease in which she removes a flapper dress to reveal a vintage 20s swimsuit. In one of the racier numbers, "Nasty Naughty Boy," Christina, dressed in a bra and shorts, brings a male audience member onstage and shows off her S&M side by using five whips and a burning Wheel of Death. Subtle. Despite her current glamorous old Hollywood look, Christina proves she's "Still Dirrty" by donning some hot lace chaps and riding a carousel horse that comes with its own built-in stripper pole. Yow!

Although the tour highlights songs from her new album, Aguilera will still belt out oldies like "Come On Over," "Lady Marmalade" and a reggae version of "What a Girl Wants." Curiously omitted from the set list is the hit that made her a household name, "Genie in a Bottle." The show will close with a double encore of "Beautiful" and "Fighter." Sing it girl!

The, er, titillating girlie show kicks off February 20 in Houston, with the Pussycat Dolls and Danity Kane rounding out the bill.
