Jessica Simpson made an appearance on "The Ellen DeGeneres Show" and announced, "I'm not pregnant..." Ellen replied, "Are you sure that you're not pregnant? I heard that you were."
"Oh, gosh!" Jessica replied. "We had an IUD. Nothing's gonna get in that uterus!"
It'd been four years since Simpson's last appearance on the show, and as Ellen reminded her, "You only show up here when you're pregnant."
But Simpson promised she's "not having a third" child. (She already has a daughter and a son with husband Eric Johnson.)
