The bad girl of pop, Ke$ha, is back with her brand new album Warrior.

The 25-year-old says she "decided that there are no rules" for the record which includes collaborations with Iggy Pop and will.i.am.

The singer who shot to fame in 2009 with her debut single Tik Tok said: "When you hear me talk about it, I think it probably sounds like a mess.

"But hopefully when you hear it, it kind of makes sense."

Despite selling more than 3 million copies of her debut album Animal, Ke$ha does not think money has changed her, saying: "I still love really terrible house parties and drinking the vodka.

"Taka vodka that's in the plastic botlle, I still drink that."
