Caylee AnthonyIt looks like Casey Anthony is about to spill the beans on the question of the century. She never testified in her murder trial, but Anthony will not be able to stay mum about what happened to daughter Caylee Anthony for much longer. She could have to open up as soon as next month!

Anthony is facing a defamation lawsuit from Zenaida Gonzalez, a woman who says she was harmed by Anthony's alleged claims that a babysitter by the same name had taken off with her 2-year-old daughter. Police later learned there was no babysitter, and Caylee's mother got in legal trouble for lying to police.

But she has never been completely clear on what exactly did happen to her daughter ... at least not until now.

According to Gonzalez' attorney, Anthony will not be allowed to plead the fifth during a deposition about the case scheduled for October 9. Said attorney Matt Morgan:

We look forward to getting answers to the questions we have had for a very long time.

Him and the rest of America.

What do you think Casey is going to say?
