Courteney Cox's daughter swears 'like a sailor'

Courtney Cox has a problem with her 3-year-old daughter Coco - the tot can't stop swearing, it has been claimed.

"She's only 3, but Coco's somehow learned to cuss like a sailor," says a source close to the actress.

And telling the foul-mouthed toddler to choose her language more carefully, has only served to make matters worse, adds the source: "Coco thinks it's funny and goes right on swearing. Courtney's just hoping she'll outgrow it.

"[Courtney] doesn't want want her saying these things to teachers or other kids."

Coco Riley Arquette is Courtney's first child with her actor husband David Arquette.

Meanwhile, the second-season premiere of Cox's FX drama 'Dirt' - which sees the former 'Friends' actress star as tabloid editor Lucy Spiller - got off to a rocky start Sunday night - averaging 1.7 million total viewers at 10 p.m, a 54 percent slide from the 3.7 million who tuned in for the series premiere in January 2007.

The episode included one unflattering shot of 43-year-old Courteney getting a painful-looking bikini wax at the beauticians.
