Ke$ha is no stranger to party girls. She appears in Katy Perry's video for 'I Kissed a Girl,' sang background vocals for Britney Spears' 'Lace and Leather' and, alongside her family in Nashville, appeared in an episode of the so-called reality show, 'The Simple Life,' which later led her to sing backing vocals for the show's star, Paris Hilton. Now, the 22-year-old singer has her very own girl-empowering party anthem in the electro pop cut, 'Tik Tok.'

"I just really wanted to embody the lifestyle that I live," Ke$ha tells PopEater about the song. "We're all young and broke and it doesn't matter. We can find clothes on the side of the street and go out and look fantastic, and kill it. If we don't have a car that doesn't stop us, because we'll take the bus. If we can't afford drinks, we'll bring a bottle in our purse. It's just about not letting anything bring you down."
