BRITTANY MURPHY IS GOING TO KEEP MOUTH SHUT ON BOYFRIENDS

Brittany Murphy

Brittany Murphy has devised a new way to keep hold of her men - keeping her mouth shut. The 'Sin City' star has a number of failed relationships behind her -including a romance with Ashton Kutcher, who is now married to Demi Moore -and believes she has been too hasty in the past to speak about her lovers. Brittany - whose engagement to movie production assistant Joe Macaluso was called off in August - is now going to remain tight-lipped when she finds a new boyfriend.The 29-year-old actress said: "I am a serial monogamist so it's hard for me to get a date as it is. One thing I did learn from my last relationship is not to speak about relationships any more."I used to be the sort of girl who would shout from the mountain tops about my latest love. But experience has taught me to be more cautious."
