Kylie Jenner wants to carve out a singing career.

The 'Keeping Up with the Kardashians' star, who is rumoured to be dating 'After Earth' actor Jaden Smith, has started taking vocal lessons, as she wants to become the next Katy Perry.

A source close to the 17-year-old beauty told gossip website ''Kylie has found her calling in life -- to be a singer!

''Kylie is now working on her first single! She is telling everyone that she knows she is going to be the next Katy Perry.''

The reality TV star and fashion designer is working with Jaden's sister Willow Smith's singing coach, Tim Carter, who is giving her private lessons at her mother Kris Jenner's house.

The source said: ''She is in training right now with vocal coach and producer, Tim Carter. Kylie has a great voice.''

Kylie hopes that her brother-in-law Kanye West, who is married to her older half-sister Kim Kardashian West, will assist her in the recording studio and also believes becoming a singer will help set her apart from her Kendall Jenner, 18, who has become a successful model.

The source said: ''She realised that she can't compete with Kendall when it comes to modelling. So she has chosen to turn to music. The whole family is really supportive of the decision, and Tim has already been to Kris' house to start the lessons!''
