Baby Watch

There's something growing inside of Rachel Uchitel ... and this time, it's not the guilt from sleeping with a married golfer.

Uchitel -- former Tiger Woods mistress numero uno -- has announced that she's preggo ... and by the looks of the photo, she's pretty convinced the baby belongs to her husband Matt Hahn.

TMZ broke the story ... Rachel and Matt secretly tied the knot back in October. The two have been living together in San Francisco ever since.

Uchitel tweeted the photos last night -- and wrote, "Expecting big things for 2012... Five down, Four months to go." By our math, the baby is due sometime around the end of April.

Congrats!

The day before confirming she was preggers, Kourtney Kardashian took her baby bump shopping in Beverly Hills on Tuesday.

The unwed 32-year-old is nine weeks along with her second child with boyfriend Scott Disick. The couple also have 2-year-old son Mason.

Dallas Cowboys defensive stud Jay Ratliff wants a judge to know ... he's willing to put in the time and the money to be a great father to his newborn son ... but he thinks his baby mama is trying to take advantage of his big, fat bank account.

Ratliff -- a 3-time Pro Bowl nose tackle who recently signed a $40 million contract extension -- was hit with a paternity suit back in April by a woman named Tonitura Kelley, who claimed the NFL star was the father of her then-unborn child.

According to court docs, Ratliff submitted to a paternity test, which revealed a positive match between Jay and the baby. Kelley filed a request for child support ... but sources familiar with the case tell us she's looking for more money than state guidelines provide for.

Jay filed docs saying he wants to be involved in the child's life -- and is making a play for shared custody. He and Tonitura are due back in court in the near future.

Ratliff's rep tells TMZ ... Jay is currently visiting with his son at least 3 times a week ... adding, "Jay's stepped up to become a good father, he loves his child ... and he's letting the judicial system run its course."

Her dad might run TheDirty.com, but Press Dahl Lamas-Richie looks clean as a whistle in her first baby photo.

"Bachelor" winner Shayne Lamas is finally a mommy ... after giving birth to a bouncing baby girl today, Press Dahl Lamas-Richie ... TMZ has learned.

We're told Shayne's hubby -- TheDirty.com honcho Nik Richie -- was in the room for the planned C-section. Press was born at 12:01pm ... weighing in at a healthy 6 pounds 6 ounces.

Justin Bieber has finally decided to address the baby daddy rumors himself -- telling Matt Lauer point blank ... Mariah Yeater is LYING THROUGH HER TEETH.

Sources directly connected with Justin Bieber tell TMZ ... the singer is adamant he never had sexual relations with the woman who claims she had his baby ... and as far as he knows, Justin has never even met her.

The woman in question reportedly filed a paternity suit against Justin, claiming she and JB had a special hug backstage at a recent concert at the Staples Center in L.A. ... and 9 months later, she popped out a baby, baby, baby, oh.

But we're told Justin believes the story was "completely made up."

Justin Bieber's legal team is ready to strike over allegations the singer impregnated a 20-year-old woman ... allegations that Team Bieber claims are "malicious, defamatory, and demonstrably false."

The woman in question reportedly filed a paternity suit against Justin, claiming she boned the underage singer backstage at one of his L.A. concerts ... and left with an embryonic party favor.

But a rep for Justin tells TMZ, "While we haven't yet seen the lawsuit, it's sad that someone would fabricate malicious, defamatory, and demonstrably false claims."

The rep adds, "We will vigorously pursue all available legal remedies to defend and protect Justin against these allegations."

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.

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.

"Bachelor" winner Shayne Lamas just treated her unborn fetus to its very first NUDE photo shoot ... and TMZ has the pics.

Lamas is weeks away from giving birth to her first child ... fathered by TheDirty.com honcho Nik Richie ... and before she pops, Shayne made sure to capture the beauty of pregnancy in all its stark naked glory.

Beyonce and her alleged baby bump (kidding!) went out for a stroll in New York City yesterday.

Sorry Internet conspiracy theorists, Beyonce's rep claims her baby bump is 100% authentic ... despite a video in which her stomach appears to fold over, leading many to believe she was wearing a prosthetic.

B's rep told ABC ... rumors about the singer wearing a fake baby bump underneath her dress are "stupid, ridiculous and false."

Also, there are photos of Beyonce in a bikini ... in which you can clearly see her actual, pregnant stomach.

So, there you have it.

We know it sounds ridiculous ... but the Internet is buzzing with rumors that Beyonce is NOT really pregnant and she's wearing a fake stomach in an elaborate cover-up. Now, a controversial new video is fueling the fire.

Beyonce appeared on an Australian TV show this weekend called "Sunday Night" -- wearing a tight red dress that accentuated her baby bump.

But when B sits down in her chair, her bump appears to collapse inward, leading many to believe it's not B's real bump after all ... but a prosthetic device intended to deceive.

So why would B fake preggo? There are rumors that she has hired a surrogate mother to carry the kid, so she won't have to put her body through the strains of pregnancy.

But color us skeptical -- because last month, Bey bared all during a vacation in Croatia with Jay-Z ... revealing what looks like a totally legit baby bump.

We called B's camp for comment -- but we haven't heard back yet.

So, we gotta ask ...

WHICH IS MORE SHOCKING -- that pregnant "Bachelor" winner Shayne Lamas is going to name her kid PRESS ... or that her unborn child is about sign a deal with a talent agency ... from inside the womb??!?!?

TMZ has learned ... Shayne and her hubby -- TheDirty.com honcho Nik Richie -- are in talks with a management company called Z Group -- which has made a formal offer to represent the baby ... even though it's still TWO MONTHS away from being born.

According to the contract, the company would get 15% of whatever the kid makes in an entertainment job ... including writer, editor, performer, musician artist, etc.
