David Caruso is breathing a sigh of relief after his ex-lover dropped her lawsuit against the CSI: Miami star.

Liza Marquez filed suit against the actor earlier this year, alleging he reneged on a deal to provide her with $1 million in financial support after their 2007 split.

The couple began a relationship in 2004 and had two kids after moving in together, but never married.

Marquez proceeded to sue for fraud, breach of settlement and emotional distress, claiming Caruso even threatened to "bury her" if she pursued him for the cash.

But last week she filed new documents to request the dismissal of the lawsuit.

Legal papers obtained by TMZ.com do not indicate Marquez's reason for dismissal, but show she "is not recovering anything of value" from the lawsuit.
