Shauna Sand to Lorenzo Lamas -- I Put a Price on Your Life ... Now Pay Up

Turns out familiarity isn't the only thing that breeds contempt ... so does not paying child support, because Shauna Sand wants Lorenzo Lamas cited for contempt of court for allegedly falling WAY behind, and also failing to maintain a million-dollar policy on his life.

Shauna claims Lorenzo is behind a total of $42,772.66 in support for their 3 daughters. She claims he's also failed to pay the $1,778 health insurance premiums for the kids.

And this is interesting ... a judge ordered Lorenzo to take out a $1 million life insurance policy for the benefit of the kids, and Shauna claims it doesn't exist.
