Johnny Depp's "greatest fear" is his children becoming actors.

The 'Public Enemies' star - who has 10-year-old daughter Lily-Rose and Jack, seven, with French singer Vanessa Paradis - is worried his children's interest in his career will see them follow in his Hollywood footsteps.

He said: "One thing is certain - neither of them will ever get bored. I always show them my various costumes and they love it. My children seem to take my job for granted. But I honestly hope that Lily-Rose and Jack don't want to become actors - that's my greatest fear!"

Johnny says his family is the most important thing in his life and he is more interested in pleasing them than winning acting awards.

The 46-year-old star explained to Germany's Joy magazine: "I'm just an actor and not a hero. It doesn't make any sense to me that I should leave the world anything. To me only one thing is really important - I want my children to be proud of me!"
