Jessica Simpson’s big baby bump has caused rumors that she’s having twins, but once again, the Fashion Star mentor put those rumors to rest on Jimmy Kimmel Live!, explaining the cause of her huge belly. 

“Apparently I have a lot of amniotic fluid, so whenever my water breaks it will be like a fire hydrant!”

When host Kimmel joked about assuming she was pregnant, Jess quipped back: 

“I feel I have a bowling ball sitting on my hoo haa!” Just another crazy quote from our fave Texas native!

As for whether she’s nervous about childbirth, the 31-year-old triple-threat starred answered, “No, I’m ready to push.”

Jessica had her baby shower over the weekend, and her sister Ashlee and friend Jessica Alba were among the guests at the party. Of course, Jess had to comment on the snacks, telling Jimmy, “I just had a baby shower yesterday which was unbelievable. It was a Charlotte’s Web thing – we had a whole fair. We had fried Oreos.”

Jessica reportedly isn’t set to deliver until April 20th, but do you think she’ll make it until then? Give us your best guess for Jess’ due date in the comments!
