This is gettin' a little nuts. It seems like all of Hollywood is getting suddenly knocked up. Nicole Richie, Jessica Alba, Matthew "I don't require a shirt" McConaughey—all members of the "how'd that happen?" club. David Spade and rapper Nelly are also presently being named as baby daddies by women from their pasts. When you become a celebrity, do you have to hand over the key to common sense?
