I am looking for the title of an old black and white comedy about two actors who were trying to have a baby and couldn't get pregnant. Then they were tried to adopt but when they took the baby and orphanage nurse back to their apt. a loud and rowdy group of actor friends were throwing them a party and the nurse got mad and took the baby back. Then they got a baby from an unwed mother but that mother took the baby back. At the end of the movie the lead faints on stage and is brought back to her dressing room. There it's discovered she is pregnant, then the family of the unwed mother gives the baby back and the orphanage aproves their adoption. It was a very funny movie, but I can't remember the title to look for it again. Any one know this movie?
