Now I know what you are thinking. Who in the world could care if Pamela Anderson is pregnant...or not? Well, you may have a point, there! She hasn't addressed the situation. Her designer/business associate Richie Rich (not the same guy in the Archie comic book series) says that she is not pregnant.
I have examined the adjoining photograph carefully (it's my job!) and I'd say that it's a possibility, even though she is not married. I've found that when famous people of Pammy's caliber deny anything, you can bet the farm that they are in denial.
I hope it's a girl!
