If you want to keep a secret, tell Ashlee Simpson! The engaged and presumably pregnant singer outfoxed Ellen DeGeneres on the host's own talk show by sidestepping Ellen's direct question, "Are you or are you not pregnant?" Ashlee replied, "Well, that has been going on for quite a while. That is something that I choose to personally not discuss." The still skinny singer then stood up and asked the audience, "Do I look like I had 10 cheeseburgers or something? Because I don't think I do!" She then promised Ellen that if she really is pregnant, she won't pull a Jennifer Lopez or a Christina Aguilera by not confirming the pregnancy until it was blatantly obvious. "I swear," said Ashlee. "I promise you that."
