Pregnant star admits it wasn't planned

Just seven months after giving birth to daughter Maxwell, Jessica Simpson found out she was expecting again.

And now she’s admitted that wasn’t part of the plan.

Appearing on US chat show¬†The Tonight Show with Jay Leno, the pregnant star says she was ‘shocked’ to find out she was going to have another child.

‘Apparently it was a part of God’s plan for my life,’ she says.

‘I was extremely shocked 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!’

She says she still hasn’t set a date for her wedding to fiance Eric Johnson.

‘We’ve had two different wedding dates, but he keeps knocking me up.

‘We’re doing it very backwards, I know… I’ll just keep my legs crossed, I guess, this time,’ she jokes.

Jessica, 32, also says she’ll be more careful with her weight gain this time around, after gaining ‘more than doctors would recommend’ while pregnant with Maxwell.
