There's one thing Brittany Murphy won't be doing in 2007 - talking about her love life in public.

Brittany says she has devised a new way to keep hold of her men - that is to simply keep her mouth shut about any developing romance.

The perky actress has a number of failed relationships behind her - including 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 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."
