Britney Spears has promised her latest tour will be "outrageously spectacular".

The 29-year-old singer is set to hit the road in June with her 'Femme Fatale Tour' and she has assured fans they won't be disappointed with her stage show, dance routines and set list.

She said: "The 'Femme Fatale Tour' will hopefully just be outrageously spectacular. I'm just hoping that the choreographers will come up with just the most outrageous things, and I'm really excited."

Britney - who will be supported by Nicki Minaj for the 26 concerts, which begin on June 16 in Sacramento - can't wait to start performing live again.

Speaking in a new video posted on her personal website, she said: "This is the most excited I've been about a project in a really long time, so I can't wait."

Britney's manager LARRY RUDOLPH has previously revealed the concerts will have a post-apocalyptic theme, to coincide with her latest single 'Till the World Ends.'

He explained: "This is exactly the direction we're moving in. 'Till the World Ends' keeps becoming a theme for us . The way we come up with a concept for a show like this is we sit with Britney, she talks to us about what she's interested in and what excites her."
