Britney Spears Promises 'Outrageously Spectacular' Femme Fatale Tour

In a new video message - you can watch below now - the singer said she was currently working on the jaunt, which takes place this summer.

"The Femme Fatale Tour will hopefully just be outrageously spectacular," she said. 

"I'm just hoping that the choreographers will come up with just the most outrageous things, and I'm really excited." 

She added: "This is one of the most excited I've been about a project in a really long time, so I can't wait." 

The tour, which will feature an apocalyptic theme, takes its title from Spears' recent album of the same name.
