Jessica Simpson Pregnant

The Jessica Simpson baby countdown is finally over -- because she just gave birth to a bouncing baby girl ... who weighed 9 pounds 13 ounces and measured in at 21.75 inches!!!

The kid's name is Maxwell Drew Johnson -- which is pretty normal by celebrity baby naming standards.

Jessica and her fiance Eric Johnson decided to use the name Drew because it's Jessica's mother's maiden name.

Jess just released a statement on her website ... saying, "Eric and I are elated to announce the birth of our baby girl Maxwell Drew Johnson."

"We are so grateful for all of the love, support and prayers we have received. This has been the greatest experience of our lives."

It's been 87 months in the works ... but IT'S FINALLY HAPPENING ... Jessica Simpson and several members of her family arrived to an L.A. hospital this morning ... because it's BABY TIME!!!!

Jessica, her mother Tina and her sister Ashlee just arrived to the hospital ... along with Eric Johnson's parents.

Jessica has looked like she's been ready to pop for weeks ... but the little Johnson inside her wasn't ready to come out.

It's POSSIBLE Jessica has already given birth ... but we just don't know yet.

So far, no word from Jessica's people.

9:00 AM PT -- Toldja so ... Jessica and her fiance just announced the birth of their baby girl Maxwell Drew Johnson.

The Jessica Simpson pregnancy saga just got even more bloated -- because the latest conspiracy theories are the most ridiculous yet! OR ARE THEY???

Jessica Simpson looks like she should've popped that baby out weeks ago -- and now her fiance is sending signals that's exactly what happened! Or we're totally misinterpreting a coffee run.

... in case you forgot.

FYI -- Jessica Simpson hasn't revealed her exact due date ... but recently said she's expected to give birth in the spring.

Just because she's very very pregnant with a bulging baby bump doesn't mean Jessica Simpson can't show off her muscular mom legs in sky high stiletto heels.

The 31-year-old mother-to-be flashed her growing belly and long stems in a printed mini-dress and a ridiculously tall pair of black stripper pumps while leaving a medical building in Beverly Hills on Thursday. Jess has killer maternal fashion instincts.

The singer/actress/style maven and her NFL fiancé Eric Johnson are expecting their first little rug rat sometime in the spring.

Jessica Simpson's pregnancy has forced forecasters to post a nationwide "Boob watch." Clearly ... THIS is what they mean by the joys of parenthood.

Jessica Simpson has finally confirmed what everyone already knew ... she's pregnant.

The singer just tweeted, "It's true ... I"m going to be a mummy!" -- posting a pic of herself in a mummy costume ... holding her baby bump.

Scary.

After months of rumors and speculation -- TMZ is proud to announce ... Jessica Simpson is absolutely, positively, 100% pregnant! Maybe.

Jessica Simpson arrived at JFK on Sunday with some extra baggage ... around her midsection.

While speculation is rampant that it's a baby bump, the 31-year-old has not confirmed if she is pregnant or not.

Looks like she may need those infamous mom jeans again after all.
