(Cover) - EN Showbiz - Ke$ha feels like shes performed well after her shows if she pukes.

The 24-year-old American singer is currently enjoying success on her Get Sleazy Tour, which kicked off last month and is set to end in May.

The tour will take her to destinations such as North America, Australia and Asia, and the star admits her performances get so wild that she often vomits when she resides to her dressing room.

If I don't come offstage at the end of the night and puke I don't feel like I've done a good job!" she laughed.

The songstress often ends up covered in bruises when shes touring, because of all the jumping around she does. The party-loving star admits there is often plenty of nudity too.

It gets manic and thrashing with pants being pulled down and everything, added Ke$ha.

The singer is famed for her unique performances, and always likes to push boundaries when shes on stage. She hit the headlines last weekend when she let blood ooze across her face an Australian festival held at Sydneys Royal Randwick Racecourse. She was performing the song Cannibal when she reportedly held an animal heart-style bag over her mouth and was left dripping with what appeared to be blood. (C) Cover Media
