Jessica Simpson had no plans to become pregnant a second time, especially six-months after she gave birth to her first child, daughter Maxwell Drew Johnson.
Jess talked about her second pregnancy and her plan to marry her fiance Eric Johnson on The Tonight Show with Jay Leno on Tuesday night.
"We've had two different wedding dates, but he keeps knocking me up."
The duo have been engaged for two-years.
"We're doing it very backwards, I know... I'll just keep my legs crossed, I guess, this time. Apparently it was a part of God's plan for my life."
"I was extremely shocked," Simpson said. "Because I was going through a lot of hormonal changes, trying to get back to the old, vibrant Jessica. You know, it was kind of like a one-night stand. And it happened, all over again!"
