She’s always up to something and last night (August 2), Ke$ha was spotted backstage ahead of her performance at Casio’s Shock the World 2010 Event in New York City.

The “TiK ToK” singer sported a rather interesting, Lady Gaga-esque ensemble complete with random spots of black paint all over her body as she posed for pictures for the press.

And during her energetic performance, the pop star made an announcement - telling the audience that she is a new Brand Ambassador for Casio Watches.

The 23-year-old songstress will be designing two Baby-G watches for Casio, which should be out in stores by next summer.
