Shirley MacLaine shocked her fans when she revealed that not only was she in an open marriage for 30 years with her former husband, producer Steve Parker but she once slept with three men in one day. The legendary actress made her jaw dropping confession to Oprah Winfrey while promoting her new book “I’m Over That and Other Confessions”. The actress now lives alone with her rat terrier and says she would rather have a good, funny, loyal dog than a man.
