A very very very … VERY pregnant Jessica Simpson dropped by “Jimmy Kimmel Live” Monday night (Mar 19).

As the “Fashion Star” judge walked onto the stage, Kimmel jokingly asked her “Are you pregnant?” to which she wittily replied, “I feel like I have a bowling ball sitting on my hoo ha!”

When she took her seat, Kimmel inquired whether she was having twins. “Apparently I have a lot of amniotic fluid, so whenever my water breaks it will be like a fire hydrant!” she replied.

Jessica is set to give birth to her first child, a baby girl, with fiance Eric Johnson in just a few weeks.
