A very glam waitressCatherine Zeta-JonesCatherine Zeta-Jones is on a mission.

And has put a ban in place in her house.

Cath's put her foot down and stopped any of her hubby's saucy on-screen antics being screened in front of the kiddiewinks.

Yep, CZJ and Michael Douglas' kiddies may not even know their papa is a big star as Cath refuses to allow them to see any of his films because they so often contain a bit of filth.

But it's OK for them to check out her flicks and they've seen their grandfather, Kirk Douglas, take to the screen too.

Cath told Tatler: "They've seen (Kirk's film) 20,000 Leagues Under The Sea, so they know about their grandfather.

Michael with wife Catherine ZJCath with hubby Michael Douglas"And they've seen me in Zorro and in Sinbad, the animated movie, which they are rather charmingly still convinced I cut my hair for.

"But they're so young, so I'm not having them seeing Michael's films with Glenn Close (Fatal Attraction) and Sharon Stone (Basic Instinct) just yet."

Quite right too, Cath.
