With the release of Britney Spears' world-awaited new album, 'Femme Fatale,' less than a month away, Spears has started pumping up the fans with song teasers and the full deluxe version track listing before it hits stores.

The 'Baby One More Time,' 'Toxic,' and 'Hold It Against Me' hitmaker promises a high-energy dance album and her own personal best with this one, which has been touched by the hands of producer Max Martin, will.i.am, Kesha, and newcomer Sabi.

'Femme Fatale' will be available in two forms -- a deluxe edition, which will feature four bonus tracks -- and twelve-song basic LP. The latter is available for pre-order purchase on iTunes now, and will include an instant download of a new song, Britney says.

"You can also Pre-Order the DELUXE version of #FEMMEFATALE and get #TILLTHEWORLDENDS immediately upon purchase....," Britney's manager, Adam Leber tweeted yesterday from the popstar's Twitter account.

Spears will perform a three-song mash-up on 'Good Morning America' on March 29 in support of the release of her much-anticipated 2011 album. 'Femme Fatale' will debut in its entirety on March 29.
