Actress Julianne Moore urges married women not to follow her character's lead in new film Chloe - and hire hookers to trap potential cheating husbands.

The Hours star insists it's always best to confront your partner if you suspect infidelity - before turning to others for help.

In Chloe, Moore hires a prostitute, portrayed by Amanda Seyfried, to test her husband (Liam Neeson).

But the actress hopes suspicious women don't take the movie home with them.

She says, "Having been married for a long time and having friends who were married a long time I can't tell you the phone calls I've gotten from somebody saying, 'Listen, I have to talk to you about this because I think he's doing X.'

"You say to them, 'Have you talked to him about it?' and they haven't. I think women do that a lot. I think we turn to our friends and say, 'He was out really late? Do you think he's seeing somebody?'

"I think there is a tendency within relationships to sometimes turn out for information with a girlfriend before you talk to your husband about it. I have seen that a lot; people asking outside the marriage for advice."

Moore has been married to second husband Bart Freundlich since 2003.
