Katy Perry is set to exercise her acting skills with a role in the big screen adaptation of classic kids' show The Smurfs. The I Kissed A Girl hit-maker recently filmed a cameo role for fiancé Russell Brand's latest picture, Get Him to the Greek, and now she's preparing to voice a character in Smurfs: The Movie.

Perry will lend her voice to the new film, which will be a mixture of live action and animation, as Smurfette, the only female Smurf among the group. She joins How I Met Your Mother star Neil Patrick Harris, Alan Cumming and George Lopez who have already signed up, according to Variety.com.

Scooby-Doo filmmaker Raja Gosnell will direct the picture and filming is slated to begin in April.
