She's at it again. Jessica Simpson is giving us too much information about pregnancy No. 2, telling Jay Leno on Tuesday that she'd like to get married, but her fiance "keeps knocking me up."

"We've had two different wedding dates, but he keeps knocking me up," she revealed, calling her latest conception the result of a "one-night stand" with her husband, Eric Johnson. Her plan to actually stick to a wedding date next time? "I'll just keep my legs crossed." Well, that should do it.

The Big O is, like, the biggest O ever!"
