David Caruso Sued by Baby Mama

David Caruso is being sued by a woman who claims the "CSI Miami" star jilted her.

Liza Marquez claims she met David on the "CSI" set in 2004 and began dating soon thereafter. She says in her lawsuit filed in L.A. County Superior Court that Caruso told her he loved her and would never leave her. She says he gave her a ring, with promises of more to come.

They began living together and he allegedly promised he would provide for her in return for her services as a homemaker and confidante. They had two kids together, and in October, 2007, upon the birth of the second child, David broke up with her.

Liza says Caruso agreed to pay her a cool $1 mil plus attorneys fees, but has reneged.

Liza says he threatened to "bury her" if she pursued the matter. She's suing him for fraud, breach of their settlement agreement, and emotional distress.
