Kim Kardashian Pregnant

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.

Kanye West insists he did NOT cheat on Kim Kardashian with a Canadian model/bartender -- telling TMZ, the woman accusing him of being unfaithful is just out for some easy publicity.

24-year-old Leyla Ghobadi recently did an interview claiming she met Kanye at one of his concerts in July 2012 -- three months after Kim and Kanye began dating. She says Kanye had his security pick her out of the crowd and they went for drinks after.

She claims they later engaged in two sexual encounters -- one while Kim was pregnant -- and that Kanye confessed his relationship to Kim was a sham in order to increase his fan base.

But a rep for Kanye says it's all BS -- telling us, "This most recent attack on Kanye West and his family is totally without merit. It's a blatant attempt by a misguided individual who is clearly seeking publicity, and another in a series of malicious stories drummed up by non-credible 'news' sources."

The rep adds, "This is a sad attempt to hurt two people trying to live their lives."

Kim Kardashian's bff Jonathan Cheban -- a regular on "Keeping Up With the Kardashians" -- found himself in the middle of an airport emergency when a woman on his plane threatened to stab him with a knife.

Cheban was flying from JFK to LAX -- when a woman on his flight tweeted at him, "Jonathan Cheban is on my flight, should I cut him with my weapon?"

She added in another tweet, "I gotta pretty intense pocket knife with mehhh."

Cheban, a former PR exec, responded, "Police?"

When the plane landed at LAX, the woman was escorted off by police and subsequently detained. We're told cops were deeply concerned about her claim that she got a knife through airport security.

She later tried to bury the hatchet, tweeting back at Cheban, "It was a bad joke ... you look really hot babe." But airport police weren't taking any chances.

Police searched the woman outside the plane and determined she did NOT actually have a knife. She was subsequently released without further incident.

Cheban tells TMZ, he never personally alerted authorities -- someone else reported the tweets -- but later in Bev Hills he admitted the incident was very "scary."

Kanye West celebrated his 36th birthday last night in New York City with the likes of Jay-Z and Nas -- but some sites are calling out the fact that Kim wasn't there ... but that's just plain crazy.

West is the headliner for tonight's Governors Ball in NYC, so he had to be on the right coast for his birthday. Kim -- who is roughly 100 months pregnant -- is in Los Angeles and cannot travel for health reasons ... so clearly she could not be there.

But while we're here, let's discuss more important things ...

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.

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.'

It's the closest thing to a Kardashian family sex tape you'll ever get ... a K-fam porn spoof -- and everyone from Kim to Kris ... and even Khloe are getting the XXX treatment.

TMZ has learned ... porn star Kiara Mia -- star of "Bra Busters 4" and "Shrimp Fried P****" -- is taking on the Kardashian fam in her directorial debut ... a parody of "Keeping Up with the Kardashians."

We're told there are no plans to mock Kim's infamous sex tape with Ray J in the film -- but a Ray-J-alike will make an appearance during a sex scene between not-Kim and not-Kanye.

A porn star playing a porn star -- doesn't get more meta than that.

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.

Kim Kardashian should think twice about taking her newborn baby on tour with Kanye West ... so says Aretha Franklin.

Aretha was out in NYC today when we told her about Kim's plans to join Kanye on his upcoming tour in October ... newborn baby and all ... and Aretha had some stern words of warning for the pregnant reality star.

Worth noting ... Aretha looked great and sounded fantastic (she even sung a few notes for us), which is notable since she just canceled two shows scheduled for next week due to unspecified "health issues."

Kim Kardashian is NOT upset that Kanye West has decided to go on tour just a few months after the birth of their child ... because TMZ has learned, she plans to go with him, baby and all.

There are reports Kim felt like Kanye was abandoning her by scheduling a tour for his new album in October -- just three months after she's expected to give birth -- but sources close to the touring company tell us, that's not true ... because Kim and the baby are coming along for the ride.

Kanye hasn't announced whether his tour will go international -- but we all know the guy has an affinity for Paris, so we're guessing he'll most likely be heading overseas.

Kanye West's pricey sports car is like his forehead ... banged up.

The full extent of the damage to Kanye's $750,000 Lamborghini Aventador was spotted for the first time in Beverly Hills today ... and it's all scratched up on the side.

On Tuesday, Kanye's Lambo was being delivered to Kim Kardashian's home after being serviced when the gate closed in on both ends of the sick ride.

Kanye is currently in New York getting ready for his gig on "SNL," so the delivery guy responsible should expect a personal performance of one of his epic live rants next week.

Kim Kardashian showed off her pregnant and smushed little piggies in L.A. on Thursday -- while Julianne Moore's Oscar nominated toes tried to make a run for it at the Cannes Film Festival on Wednesday.

Question is ...

Kanye West is having a bad month -- his $750,000 car just crashed into Kim Kardashian's gate.

Kanye's Lamborghini Aventador was being delivered to Kim's L.A. house after getting serviced. We're told the driver pulled into the gate but didn't make it all the way in before the gate closed on both sides of the car.

Kanye's in NYC, healing from his run-in with a sign in Beverly Hills.

As for the damage, we're told a very nervous repair shop has sent a detailer over to see if the damage can be buffed out.

Buffed out or snuffed out. Kidding!

Kim Kardashian is turning into a real bad ass ... she's telling friends she thinks Kanye West was spot on when he lunged and swore at a paparazzo in Bev Hills.

Kim -- who is always impervious to the gaggle of photogs who chronicle her every move -- thinks Kanye was justified when he bolted out of a restaurant and went all Incredible Hulk on an unsuspecting camera guy.

As you know ... Kanye had a close encounter with a metal sign as he walked to 9021PHO, slamming his forehead UFC style with a souvenir that will probably last for a week.

Kim is telling friends ... the paparazzi have become increasingly aggressive with both of them since she became pregnant. She's especially upset because on Monday a photog chased her down while she was driving and she had to swerve into another lane to avoid him and almost got into a bad accident.

Bottom line ... Kim is encouraging Kanye to take care of business when a photog crosses the line. The problem with her theory -- in the case of the sign, the photogs held their distance and Kanye just didn't look where he was going.

The truth hurts.
