Ke$ha fans can't get enough of her "$leazy" antics! 

After dominating the charts last year -- her debut single "TiK ToK" was declared 2010's biggest selling digital song in the world -- the glittery sensation has a headlining tour that's already sold out!

Ke$ha's "Get $leazy" tour opens in Portland on February 15. Meanwhile, her new single "Blow" hits radio stations next week.

The singer is well known for her off the track fashion sense, which she describes as "garbage chic." See her wild style in ET's Most Outrageous Red-Carpet Outfits gallery.
