DETROIT  - Ke$ha says her upcoming Get $leazy theater tour will be "a ridiculously fun dance party" that will build on the energetic sets she played while opening for Rihanna last summer.

"Visually it will just be assaulting, and sonically it will be assaulting. It's just going to be an assault of all your senses, but it's going to be really, really, really fun," the chart-topping "TiK ToK" singer tells Billboard.com.

Ke$ha also hopes that Get $leazy, which gets underway February 15 in Portland, Ore., will "be surprising because I'm going to show people a few more aspects of my musicianship and personality that you might not be expecting. I play a lot of instruments ... and I can dance and I can really, really sing, so I'm going to be doing all that and, meanwhile, covering everybody in glitter."

The tour's repertoire will come from Ke$ha's two 2010 releases -- January's "Animal," which has sold 1.16 million copies according to Nielsen SoundScan, and November's "Cannibal," which failed to crack the top 10. She also plans to film portions of the tour, both onstage and off.

The Get $leazy tour is currently booked for two North American legs, separated by a swing through Australia and Japan in March. It wraps May 6 in Los Angeles. Ke$ha expects to play more international dates after that, but none have been announced yet.
