Gamblers might have guessed a pregnant Jessica Simpson would give birth some time in February or March, but the blonde fashion mogul is still sporting a huge baby bump and rumor has it that she will not deliver her baby girl for another month.

Only one month to go! the 31-year-old was overheard saying at Fred Segal's in Santa Monica on Tuesday according to Us Weekly.

I can't wear heels anymore, said the star, who wore a flowing maxi dress and flip flops. I tried but it was too hard. Wearing heels is like a religion to me, so it's tough! Simpson swore that she would wear heels in the delivery room, but it seems as if the singer has taken all she can handle.

Back in November, Jessica Simpson swore she would give birth in four-inch YSL heels. I'm probably going to deliver my baby in [4-inch YSL heels]... I went to the doctor yesterday and he said, 'You're gonna need to get out of those heels!' she joked to Us Weekly just one month after announcing her pregnancy in October. 

It's like carrying a bowling ball! Simpson was reportedly overheard saying of her huge belly last week. Almost done!

Throughout her seemingly never-ending pregnancy, Jessica Simpson has been quite vocal and quite blunt about her life as a pregnant woman. She posed naked on the cover of Elle magazine, dished about eating cheesecake for breakfast and even talked about her excessive amniotic fluid.

Here are some of Jessica Simpson's most brazen quotes about her pregnancy yet.

I feel like I have a bowling ball sitting on my hookah. Apparently I have a lot of amniotic fluid, so whenever my water breaks, it will be like a fire hydrant! Simpson told Jimmy Kimmel during an interview on Jimmy Kimmel Live.

I just started calling myself Swamp A--. Like, I have 'swamp a--' right now. I had major swamp a-- because I was wearing these Spanx to hold in my gut. It's like the bayou up in that region, the mom-to-be told Jay Leno during an interview on The Tonight Show.

There is only one, there is only one girl ... But I did get knocked up by a baller ... A big football player, Simpson told Ellen DeGeneres during an interview on The Ellen DeGeneres Show.

We were goin' to have an all-day drinking binge ... Gonna ride our bikes, hang naughty things. But I started feeling this overwhelming guilt, Jessica Simpson told Elle about finding out she was pregnant.
