My Name is Earl star Jaime Pressly announced on the The Tonight Show With Jay Leno last night that she's four months pregnant. The emmy nominated actress told the audience that she has had a pretty uneventful pregnacy with the exception of: "The mood swings you can't do anything about. You want to stab people and you don't know why!" Note to self: Stay out of Jaime Pressly's way for the next five months.
