Katy Perrt visits 'Jimmy Kimmel Live!'.

Katy Perry is going the extra mile to ensure that her upcoming ‘Katy Perry: Part of Me 3D’ movie will be a hit. For her latest promotional appearance, the colourful singer visited ‘Jimmy Kimmel Live!’ to talk about the film, which will debut on July 15th.

Last week, Perry checked in to ‘The Tonight Show with Jay Leno’ to chat about ‘Part of Me 3D’ but she shared just a bit more information on ‘Jimmy Kimmel’. Speaking about her past, Perry joked about how clever 91-year old grandmother, her parents strict Christian upbringing and how they kept her from watching the ‘Smurfs’ cartoon. Yes, you read that correctly, the ‘Smurfs’.
