Baby Watch

Kim Kardashian has given birth to a baby girl ... TMZ has learned.

Source close to KK tell TMZ ... it was a NATURAL CHILD BIRTH. She started having contractions Friday night and went into full labor early Saturday AM.

Our sources tell us the baby and Kim are both in good health. We're told Kim delivered the baby at Cedars-Sinai Medical Center this morning ... 5 weeks early.

Our sources say BF Kanye West was there for the entire thing -- in the delivery room by Kim's side. We're told Kanye cancelled his appearance at his own record release party last night when Kim told him she was feeling "a little off."

It is the first child for Kim and Kanye.

Here's ready-to-burst Jamie Lynn Sigler wearing a bikini at a North Carolina beach last week. She's 7 months pregnant ... and we're really kinda into it? Is that weird?

Jessica Simpson was involved in a dastardly conspiracy with OK! Magazine to make a buck by grabbing a man's baby and mugging with the infant for the camera, making it appear as if the child were hers ... this according to a bizarre new lawsuit.

According to lawsuit uncovered by The Times-Picayune in New Orleans, Christopher Hurst took his teenage daughter and infant son to a department store in October 2011 to meet Simpson.

The lawsuit claims ... when Hurst got close to Simpson, a stranger suggested he hand his infant over to Simpson ... who was pregnant at the time.

Hurst obliged, and then, according to the suit, a photog came out of nowhere and began snapping pics.

According to the suit, Hurst was stunned months later when OK! splashed the pic on its cover, making it appear it was Jessica's baby. The irony -- Jessica's baby wasn't even born yet.

The lawsuit accuses Jessica of being in on the plot, claiming she had a deal with a competing mag to sell the first baby pic for $800k, but then got greedy and hatched a plot with OK! to double dip with a baby that wasn't even hers.

Hurst is suing Simpson, OK! magazine, and Getty Images for damages in excess of $75,000.

Touring is tough, and Beyonce's figure out a way to keep the heat on ... in a good way.

B posted a photo of herself with her only child, Blue Ivy, relaxing in a jacuzzi.

It's clear from the photo, mother and daughter are crazy in love.

Kim Kardashian did her best to keep the goings on inside her baby shower yesterday a secret, but she failed to wrangle her crazy Aunt Karen ... who blabbed all about the party to the paps ... but some of what she said was just plain wrong.

Karen Haughton, who is Kris Jenner's sister, clearly had a good time and was as chatty as can be as she made her way out. She struck up conversations with photogs and posed for pics with fans ... all while she spilled details of what went on inside.

Karen -- who may have had a mimosa or 2 -- had a couple of teeny-weeny facts wrong:

-- She said the guests scored Rolexes as shower gifts (not true)
-- Kanye and Kim are the same height (not true)
-- She says she ate cake, and then seconds later said there was no cake, just cookies

Bruce Jenner's memory is disappearing faster than Kim's figure ... because the Kardashian patriarch has met Kanye West SEVERAL times, despite claiming he's only met the rapper once -- and Kim is pissed at her stepdad for saying it.

We've done our research -- and came up with at least FOUR different occasions where Bruce and Kanye were both present ... Kourtney's baby shower in May 2012, a taping of "X Factor" in November 2012, a Clippers game in December 2012, and the Kardashian family Christmas party.

The photographic evidence contradicts what Bruce told Extra this weekend ... that he only met Kanye once in his entire life, saying, "[Kanye is] not around."

We're told Kim's upset with her 63-year-old stepdad ... because Bruce makes it sound like Kanye doesn't care about the family.

And here's a clue that maybe Bruce isn't so into Kanye -- back in April, 2012, he said he was "not that excited" when Kim started dating the rapper ... because he felt Kim was rushing into a new relationship too quickly after leaving Kris Humphries.

Crazy week for celebrities ... and speaking of crazy, we gotta ask ...

Rather than simply come out and say "I am not pregnant" ... Beyonce chose to deflect the rumors once again ... this time by posting a photo of her drinking a glass of wine with hubby Jay-Z.

Rumors of Bey being knocked up have been swirling for weeks, beginning when she canceled a concert in Belgium and cited the dreaded "exhaustion and dehydration."

She also posted (and quickly deleted) a diatribe on Instagram slamming the rumors ... but at no point has she ever denied them.

This photo doesn't put the rumors to rest either ... doctors aren't completely against a pregnant woman having a glass of wine every now and again. So we ask ...

Here's a glowing Kim Kardashian in the middle of nearly flashing her pregnant goods in Santa Monica on Wednesday (left) -- and the now infamous and controversial JCPenney tea kettle (right).

All hail, Kim Kardashian.

A wardrobe malfunction turned Kim Kardashian into the brunette Marilyn Monroe.

While walking around Santa Monica in flats on Wednesday, the pregnant 32-year-old let a breeze get the best of her maternity dress ... and almost flashed more than just her baby bump.

Although she's no stranger to showing off the goods, Kanye West's baby mama recovered in time to make sure the photo was rated PG.

Even when she attempts to keep her maternity style casual, Kim can't help but make a spectacle.'

Jessica Simpson is a huge star and it shows.

Wearing a slimming black sheer frock, the glowing mom-to-be successfully maneuvered her growing baby bump through the streets of Ojai, California this weekend.

Although she looks like she's about to pop, the 32-year-old singer/actress/fashion mogul -- who already has an adorable one-year-old daughter -- isn't due until around July.

While Jess has revealed she's having a boy this time, it is going to be a belly long month or so until he finally arrives.

An intrepid TMZ Tour passenger spotted Halle Berry inside a Fed Ex Office yesterday in Hollywood ... and captured a great moment when her daughter Nahla started giving their bodyguard the cutest looks imaginable.

Halle Berry knows nothing shows off your maternal figure quite like a little black baby bump dress.

The gorgeous 46-year-old mom-to-be kept her growing curves chic and simple in a sleeveless stretchy frock as she ran some errands in Sherman Oaks on Tuesday.

It's been nearly seven weeks since Halle revealed she was carrying her second child and it's pretty obvious pregnancy agrees with her.

The glowing Oscar winner is due in the fall, so she's sure to have a belly nice summer.

Just how over the top were Kim Kardashian's music-box baby shower invitations? Really, really, really over the top -- and TMZ has the first photo proof.

The invite to Kim K's June 2nd bash -- sent to a guest close to Kanye West -- arrived as a fully functional music box, complete with a spinning ballerina ... dancing to a lullaby version of Kanye's "Hey Mama."

Not only is the invite playing the baby daddy's tune, but the ballerina bears a striking resemblance to Kim herself -- just in case anyone forgets who this party is REALLY celebrating.

According to the invites, Kris Jenner, Shelli Azoff (wife of uber-manager Irving Azoff), Kourtney and Khloe Kardashian are hosting the party. Recommended attire ... garden chic. We think that's rich people speak for casual.

Now here's the "Hey Mama" lullaby -- listen and pretend like you were invited.

Pregnancy rumors be damned, Beyonce wore a slew of form-fitting outfits during her tour stop in Milan last night.

Bey has thus far neither confirmed nor denied the rumors, only attacking the press with an Instagram post she quickly deleted. Multiple outlets say they have confirmed Mrs. Carter is pregnant with baby #2, and many point to the fact she canceled a show last week ... citing good ol' "dehydration and exhaustion."

When we asked yesterday, 81% of you said you thought Beyonce was preggers. After looking at these pics, we ask again ...
