Caroline Rhea and her longtime boyfriend, Costaki Economopoulos, welcomed their first child on Monday in New York, her rep tells PEOPLE.
Ava Rhea Economopoulos came into the world weighing 8 lb., 15 oz. and measuring 22½.
"We wanted the shortest first name possible, since her last name is the alphabet," says the new mom, 44. "It was either that or Emmy, because I've always wanted an Emmy."In addition to her successful stand-up career, Rhea has appeared on such TV shows as Sabrina, the Teenage Witch, hosted The Caroline Rhea Show and stars in the Logo Network series, Sordid Lives.
Economopoulos is also a comic and a weekly contributor to the nationally-syndicated Bob and Tom radio show.
