On July 29, 2011 audiences will hear Katy Perry’s voice in a whole new way: as the voice of Smurfette in 'The Smurfs' co-starring with Neil Patrick Harris.Perry was not only involved in providing the voice for Smurfette, but says that she helped with the development of her character as well. "When I'm doing the voice for Smurfette it's really interesting because I get to be a part of creating her character and adding little nuances to her who I guess she is on the big screen. The voice is basically my voice but throw some rocks in it.  Just a little bit rockier." Perry also believes that the film will be a big hit with kids and adults alike. "It's a positive story and it has a sweet side and there's a great message," Perry says. "It's one of those you can't go wrong type of films. I think it's very family oriented and that's why I wanted to be a part of it." (ETonline.com)
