Baby Watch

Snooki is in the midst of a MAJOR transformation ... from a sloppy, smooshy drunken idiot ... to a RESPONSIBLE mom-to-be who's taking her pregnancy very seriously ... TMZ has learned.

Sources close to the MTV star tell us ... ever since Snooki discovered she was with child she quit drinking, quit screwing around ... and has convinced the people around her that she could develop into "mother of the year."

We're told Snooki comes from a loving family ... she's very close with her mom ... and she completely understands what it takes to become a responsible mother.

The timing of Snooki's pregnancy couldn't have worked out better ... 'cause we're told the premise of her upcoming "Jersey Shore" spin-off reality show with Jwoww is "the last hurrah."

Sources connected to the production tell us the show will follow the girls as they transition into adulthood ... move into an adult apartment ... and take some serious adult steps with their boyfriends.

We're told the boyfriends will not have starring roles on the show ... but the relationships will be "key."

As for Snooki, we're told she has no plans to marry her BF ... yet ... even though he's most likely the baby daddy.

The Situation is definitely NOT to blame for the mini-guido baking inside of Snooki's womb ... this according to Sitch's BFF.

"The Unit" -- aka Jonny Manfre -- just called in to “Big Poppa” Gary Spears at KISS-FM in NY ... and said there is absolutely NO baby daddy controversy ... despite the fact Snooki allegedly got all smooshy with Sitch in the past.

"It's not Situation's baby ... I'll tell you that much ... I would assume it's Jionni's baby." Unit is referring to Snook's BF, Jionni Lavalle.

Forget boozy nightclubs and bar fights -- mama Snooki's new "Jersey Shore" spin-off will be all about the guido growing in her uterus ... in fact, one Jersey City baby store has already been contacted by producers about shooting on location.

The owner of Bambi Baby tells TMZ, someone from 495 Productions -- the company behind "Jersey Shore" -- reached out to the baby store within the last few weeks ... right around the time Snooki was adamantly denying she was pregnant.

Wearing a loose fitting top for two, newly pregnant Snooki tried to shield herself from the rain underneath her coat as she filmed her new reality show in Jersey City on Wednesday.

As TMZ reported earlier, Snooks originally lied about being with child because she didn't want to jinx anything prior to being three months pregnant. Now that she's passed that threshold, an official announcement is expected at any moment.

Snooki was LYING FOR TWO when she denied pregnancy rumors earlier this month ... but sources tell TMZ the "Jersey Shore" star had a damn good reason -- she didn't want to jinx herself.

Sources close to the MTV star tell us ... Snooks WAS already pregnant when she went on Sirius/XM radio on Feb. 1st and told everyone she was OUTRAGED by the suggestion that she had preggo belly.

But we're told Snooki is taking the situation very seriously ... especially the taboo about revealing the pregnancy before the 3rd month.

Now, it seems Snooki has crossed the 3-month threshold ... and an official announcement could come any moment.

Drew Barrymore was clutching what appears to be sonogram results as she left a doctors office in Beverly Hills with her fiance late last week ... soooooo ... is Drew pregnant?!?!?

Here are the facts:
-- Drew is engaged to Will Kopelman, a 34-year-old art consultant ... who popped the question just a few months ago.

That's pretty much it for the facts.

We reached out to Drew's rep -- who politely gave us a "no comment" ... but it ain't exactly a denial.

So ... congrats?

This is what the heir to a hip-hop fortune looks like ...

Beyonce and Jay Z have finally posted photos of Blue Ivy Carter .. which appear to have been taken at their pimped out suite at Lenox Hill Hospital in NYC.

The Carters posted a note along with the pics which reads, "We welcome you to share in our joy."

Blue Ivy was born on January 7th.

It appears Beyonce color coordinated for the shoot with Blue Ivy ... check out her blue fingernail polish.

Snooki is calling radishes on a report that she's pregnant -- claiming not only is she NOT pregnant, she's insulted by the insinuation she's fat.

The "Jersey Shore" star left Sirius XM studios in New York moments ago -- where she appeared on the Opie & Anthony radio show -- and a photog flat-out asked if the pregnancy rumor was true ... Snooki firmly replied, "NO!"

Worse, Snooki's livid at rumors she's gained weight, claiming, "Why are people calling me fat? That's so rude!" Snooki said she does wanna get pregnant one day though ... when she gets married.

As for the Opie & Anthony interview (below) -- Snooki said the media outlet that reported the story is just like one of the bullies who terrorized her in high school ... and she has a message for the offender ... "I hate you."

Check out the vid for Snooki's Super Bowl favorite. You won't believe it.

... 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.

If you were surprised to hear Kristin Cavallari was pregnant with Jay Cutler's baby, you're not the only one -- the couple themselves were shocked by the news ... TMZ has learned.

Jay and Kristin announced yesterday they were with child -- following a crazy few months where they broke off their engagement, only to announce it was back on.

Sources close to the couple tell TMZ, K&Jay had discussed the possibility of kids -- but planned to start cranking 'em out in a few years ... not any time soon.

But shocking as it was, we're told they're thrilled with the news ... renewing their commitment more than ever to making their relationship work.

If Jay wasn't locked down before, he sure is now.

Just one day after announcing her pregnancy, a freshly knocked up Kristin Cavallari ventured out in the L.A. rain this morning -- grinning with pride over the embryonic cells rapidly splitting in her uterus.

25-year-old Kristin and her 28-year-old baby daddy Jay Cutler broke off their engagement in July -- but rekindled things shortly after in November ... with a vengeance, apparently.

Rachel Uchitel showed off the unborn baby female fetus growing inside her by rockin' a sexy two-piece bikini in Cancun the other day.

The 36-year-old former Tiger Woods mistress bronzed her five months pregnant bones while vacationing with her husband Matt Hahn.

Beyonce finally popped, giving birth to a baby girl named Blue Ivy Carter in New York City on Saturday

Proud dad Jay-Z, real name Shawn Carter, was at the hospital where Beyonce reportedly birthed Ivy by c-section -- and shortly after her arrival ... J & B's famous friends started sending out birth announcements on the Internet.

Rihanna tweeted, "Welcome to the world princess Carter! Love Aunty Rih"

Hip-hop mogul Russell Simmons also took to Twitter, saying ... "congrats to my good friends Beyonce and Jay-Z."

Beyonce famously announced her pregnancy on stage at the MTV Video Music Awards back in August.

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.

In case the picture didn't give it away ... Rachel Uchitel IS HAVING A BABY GIRL ... TMZ has learned.

Sources connected to the former Tiger Woods mistress tell us ... Uchitel and her husband Matt Hahn are very excited about the female bundle of joy ... and they're already stocking up on gifts for the little she-fetus.

As we previously reported, Uchitel is 5 months into the pregnancy ... and is expected to give birth at the end of April.

Rachel Uchitel ain't planning to be a full-time breast-feeder when her baby is born -- TMZ has learned, she's asking friends to buy her a $300 nipple pump instead ... on top of several other extremely expensive baby goodies.

Rachel -- who announced her pregnancy last night on Twitter -- posted a baby registry online recently, asking for a laundry list of newborn crap .... including the nipple pumps, a $500 high chair, a $300 car seat, TWO strollers ... one for $400, and one for $1000, and $300 cashmere bedding.
