Rumors have been circulating suggesting Simpson and her fiance, Eric Johnson, are expecting a baby boy to join their daughter, Maxwell, but the blond beauty admitted she had no idea how the information leaked.
She joked, "I don't think that a lot of stuff people say is malicious in any way, but maybe I have some friends with some big mouths. (Maybe) they call up people, tell their parents, and the parents talk about it at the grocery store. Who knows?"
Simpson's daughter was born last May, while her second baby is due this summer.
