Denise Richards is expecting a baby - she thinks her pet pig is pregnant. The actress owns male and female Vietnamese pot-bellied pigs and was shocked when she stumbled in on a sex session.

She says, "My Charlotte maybe pregnant. I walked in on Charlotte... I had no idea that pigs go into heat at three or four months."

Richards reveals her new pets will play a large part in her upcoming reality TV show.

She explains, "I've always wanted a pot-bellied pig because I think they're so cute. They're like dogs. They're very clean."
