The mom from "My Big Fat Greek Wedding" racked up a big fat nursing bill while recovering from a car crash, but never paid up ... so she's been hauled into court.
Lainie Kazan is on the receiving end of a small claims court lawsuit, filed by Dynamic Nursing Services, which claims she stiffed them.
You'll recall ... Lainie was in a bad crash back in April that left her in a neck brace. Dynamic Nursing says it helped nurse her back to health ... then got left hanging to the tune of $2,762.
Lainie has a court date later this month. We reached out to her ... so far no word back.
