Baby Watch

Only one of them is really pregnant at the moment, but Snooki and Jwoww both got practice being moms as they were spotted holding fake babies while filming their new "reality" TV show in Jersey City on Thursday.

Reese Witherspoon turns 36 today ... and she may be getting the best birthday gift ever if she really is carrying her first child with husband Jim Toth.

The same day news of her pregnancy was reported, Reese was spotted in a loose fitting black top and red skirt in L.A. on Wednesday.

While the Oscar winner has yet to confirm the baby news, she already has two kids with ex-husband Ryan Phillippe.

Mom-to-be Snooki enjoyed her first sober Spring Break party in Cancun today ... while her "Jersey Shore" spinoff castmate Jwoww enjoyed the kind of cocktail an unwed pregnant reality star cannot.

With her unborn baby girl due next month, a very pregnant Rachel Uchitel and her hubby Matt Hahn walked the streets of San Francisco on Tuesday.

Elizabeth Berkley is with child ... this according to Elizabeth Berkley.

The former "Saved by the Bell" actress -- married to artist Greg Lauren -- debuted her baby bump in L.A. today. It's the couple's first child.

Obviously, the 39-year-old is super fired up about the situation ... telling TMZ, "In life there are moments you cherish forever and this is one of them."

She adds, "We are so excited to share this moment and special news! The baby is due this summer"

Mazel tov!

Snooki's ex-BF Emilio Masella says he's just a schmuck who misspoke when he wished a "miscarriage" on the MTV star ... but says he still HOPES TO GOD she's not really pregnant.

Emilio just called in to "TMZ Live" to explain himself ... saying, "What I meant by the statement was that I hope she doesn’t have the child. I just hope the test was wrong ... I think she's too young. I don’t think this kid is in it for her."

He continued, "If she's pregnant with this kid I guess I can't associate with her."

Before Snooki's ex-boyfriend wished death upon her unborn fetus, the "Jersey Shore" star took preemptive measures to make SURE he never badmouthed her -- in the form of a nasty legal threat -- but clearly, the guy wasn't intimidated.

TMZ broke the story ... ex-BF Emilio Masella said he hopes Snooki "has a miscarriage" to save herself from a pregnancy she's not ready for.

But here's the thing -- a month before he made that comment, he told another media outlet he could easily be Snooki's baby daddy too ... implying he recently slept with her.

The comment didn't sit so well with Snooki's lawyers, who responded with a cease and desist letter on February 1st -- threatening to sue if he continued to badmouth Snooki OR her pregnancy to the media.

Her lawyers were pretty clear -- "Demand is hereby made that you cease and desist from making any additional public statements regarding Ms. Polizzi that could in any way be taken to be offensive by her."

Snooki's ex-boyfriend Emilio Masella doesn't think the world is ready for Snooki spawn ... including Snooki herself -- telling TMZ, "I hope for her sake ... not to be rude or anything ... but I hope she has a miscarriage."

Emilio tells us he does believe Snooki will eventually be a good mother -- but insists ... there's no way in fist-pumping hell she's ready for it now.

According to Emilio, Snooki has always been flippant about having kids ... and never really grasped the gravity of being pregnant -- "When I was with her, she said she wanted twins. She would always say 'Let’s have twins.'"

Emilio says, "I would def recommend her to get a paternity test to see who the father is because I’m sure there are other subjects" -- adding, "Vinny could easily be the father."

As for how Snooki and BF Jionni's relationship will pan out on her new spin-off show -- Emilio thinks the two will get married ... but Snook will "pull a Kim Kardashian."

Emilio says, Snooks is "going to have the baby and break up with him right after."

Cease and desist letters don't scare Emilio -- turns out Snooki's lawyers secretly threatened to sue him LAST MONTH if he ever offended Snooki in the media again ... clearly, he wasn't intimidated.

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?
