David Caruso probably feels like a million bucks right now -- 'cause we've learned his baby mama just dropped her million dollar lawsuit against the actor.
Liza Marquez, the mother of David's two children, filed documents in Los Angeles Superior Court last week requesting the dismissal of her mega-sized lawsuit against the "CSI: Miami" star.
The doc states Liza "is not recovering anything of value" from the lawsuit.
As TMZ first reported, Marquez claimed Caruso promised to give her $1 million plus attorneys fees when the couple split -- after the birth of their second child.
When he allegedly didn't pay up, she sued for fraud, breach of settlement, and emotional distress.
It's unclear why Marquez dropped the suit.
