Kylie and Kendall can't remember life before fame!

Los Angeles - Kylie and Kendall Jenner can't remember life not on camera.

The teenage reality stars have appeared on family show Keeping Up with the Kardashians since they were 10 and 12 years old respectively and don't know what life is like out of the spotlight.

Kylie, 17, said: "I don't think we really remember a time before the cameras."

And 18-year-old Kendall added to DuJour magazine: "Even before the show, when we were babies - four or five years old - we'd be walking red carpets with our dad, Bruce Jenner."

It was recently claimed Kendall wants to quit Keeping Up with the Kardashians because she is concerned it could affect her modelling career.

A source said: "She has been advised by friends in the fashion industry that reality TV could damage her modelling career."

While Kendall is contractually bound to finish filming the latest series of the show, she has pulled out of appearing in any spin-off programmes.

The source added: "Kendall had the option to pull out of any other potential shows and that's exactly what she's done."
