Jessica Simpson on Fiancé Eric Johnson: 'He Keeps Knocking Me Up' (VIDEO)
The mom-to-be chats with Jay Leno about second pregnancy, sitcoms and staying healthy.
Throughout their two-year engagement, Jessica Simpson and fiance Eric Johnson have tried to get married, but there's been a few speed (err, baby) bumps along the way.
"We've had two different wedding dates, but he keeps knocking me up," the expectant star joked Tuesday on The Tonight Show with Jay Leno.
"We're doing it very backwards, I know...I'll just keep my legs crossed, I guess, this time," said Simpson, who flaunted her pregnancy curves in a low-cut leopard print dress.
"Apparently it was a part of God's plan for my life," she said with a laugh. "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!"
This time around, Simpson is vowing to maintain a healthier lifestyle after gaining "'a lot more [weight] than doctors would recommend."
"I was really happy to be pregnant and I didn't ever step on the scale," admitted Simpson, who was criticized for her eating habits while pregnant with 8-month-old daughter Maxwell. "I didn't realize you could gain that much weight that quickly."
"I didn't really make any healthy good decisions," she added.
With her family life keeping her busy, the proud mom is taking on one additional title: soon-to-be TV star.
Simpson is currently ironing out the details for her in-the-works NBC sitcom, which is loosely based on her real life.
"About a girl getting pregnant?" asked Leno.
"Yes," Simpson replied about her return to the small screen. "Yes, and how that girl deals with that and everything else...I will be playing myself, which is pretty easy."
But don't expect Simpson to name her new show Jessica.
"No...We don't have a name yet, we're just now in the process of casting everyone, doing the pilot. I will be playing myself but we'll have actors playing Eric and my dad. That'll be funny," she said.
