Katy Perry has been discussing the differences between careers in acting and in music.

The American pop star, who recently voiced the character Smurfette in ‘The Smurfs 2’, has stated that acting is not a profession to be taken lightly.

Speaking to Radar magazine Perry revealed: “It's definitely a lot of effort to be an actor, and it's not something just anyone can roll into.”

The ‘Firework’ star also blasted those in the entertainment industry who think it’s easy to master both music and acting, as she argued: “I think you get a lot of people thinking, 'If I can act, I can sing; if I can sing, I can act', and it's just not true.”

Katy also divulged that she may not have the required level of dedication required by the film business: “I think that it's actually harder and it takes more time than a music career. You wake up at four or five am. That's commitment. If the movie would start filming at 11am then I would do it.”

Another non-music related project Perry has been working on is her latest fragrance called Killer Queen.
