Cara Delevingne thinks Kendall Jenner should launch a movie career.

The British supermodel has recently made a move into acting and has advised her friend - who shot to fame on 'Keeping Up With the Kardashians' before becoming a model - to follow in her footsteps and it is now looking increasingly likely the 19-year-old beauty will quit her family's reality show.

A source said: ''It seems some people in the fashion world have advised her to quit the show. She's been advised to focus on fashion rather than making herself available for filming at the drop of a hat.

''Cara has been encouraging her to move into acting too. If there's a possibility of a film career, she needs to distance herself from the reality TV world now.''

Though Kendall hasn't yet made a decision on her future, show bosses at E! seem resigned to the fact she will be departing 'Keeping Up with the Kardashians'.

An insider told Grazia magazine: ''Everyone is convinced it's only a matter of time before Kendall quits. She's got so much else going on - she's never in LA.''

Another source added: ''Kendall is more in demand than ever. She's getting booked for modelling jobs all over the globe. It seems she's got to prioritise.''
