On Monday, Katy Perry attended the photocall for her new film "Katy Perry: Part of Me" in Rio De Janeiro in a sexy yellow cut-out dress and studded red high heels.

Later she attended the film's premiere wearing a long, shiny silver dress. The red carpet was decorated with giant lollipops and a huge image of the pop star next to her guitar.

The film takes fans behind the scenes of her "California Dreams" tour.

Katy has been showing off a lot of skin lately. Over the weekend she hung out at a Miami hotel in various bikinis.  She has also reportedly been hooking up with singer John Mayer. She just recently finalized her divorce from British actor Russell Brand.
