Last night Jessica Simpson was a guest on the 'Tonight Show' with Jay Leno and spilled the beans on all that's happening in her life right now.

First and foremost, she chatted about the pregnant bikini pic that caused a firestorm on Twitter, a candid image that she captured while vacationing in Hawaii over the holidays.

She revealed to Jay, “I felt really hot, and I thought I deserved a Kim Kardashian moment, you know? I was really feeling it, like, ‘Oh, my bump looks cute. I’m going to share that.'"

Jessica admitted that the second pregnancy wasn't planned and came as a total surprise to her and fiance Eric Johnson.

“Apparently it was a part of God’s plan for my life,” Simpson says with a laugh. “I was extremely shocked. I was shocked because I was going through a lot of hormonal changes trying to get back to the old, vibrant Jessica. And you know, it was kind of like a one-night stand. And it happened … all over again!”

Their daughter Maxwell Drew is 8-months-old and Simpson admits that during the pregnancy she went on a full blown feeding frenzy, "I didn't really make any healthy, good decisions."

After a successful stint on Weight Watchers that helped her lose 50 pounds, she plans to do better this time around.  She's currently dealing with morning sickness and has had no cravings.  Jess is due to deliver a summer baby and is excited to start feeling good.

As for marriage, the fashion designer has already set two wedding dates but was forced to call off the nuptials again because she keeps getting "knocked up."  She claims that after giving birth in July "I'll keep my legs crossed this time."
