Baby Watch

Kanye West isn't wasting any time getting back to work ... heading into the office just a day after welcoming his new baby girl.

West was spotted outside his Calabasas studio Tuesday -- and while he stayed quiet -- he still cracked a big smile when photogs congratulated him on the birth.

TMZ broke the story ... Kim and Kanye were in the hospital room when their surrogate gave birth to a 7 lbs 6 oz girl at Cedars-Sinai early Monday morning. Kim was the first to have skin-to-skin contact with the baby, and Kanye held her shortly after.

Still no word on a name.

Kim Kardashian and Kanye West just had their third child via surrogate ... TMZ has learned.

Kim made the announcement, saying the surrogate gave birth Monday to a healthy girl weighing 7lbs 6oz.

TMZ broke the story ... Kim and Kanye used a surrogate because she has placenta accreta ... a life-threatening condition that created serious complications during the birth of her second child, Saint.

The surrogate lives in the San Diego area ... it's unclear if she gave birth there or at Cedars-Sinai in L.A. ... where the couple's other two children were born.

Kim Kardashian was taken by surprise by a flash mob Thursday, but what's even more head-turning is her very pregnant sister, Khloe, jumping in on the routine ... IN HEELS!

Kim, Kourtney and Khloe hit up the Topanga Mall in the San Fernando Valley. Cameras were with them, so they were likely shooting for 'KUWTK.'

We're told Kourtney and Khloe organized the dancers as a surprise for Kim. And while Kourtney looks smokin' hot nailing all the moves, it's hard to ignore Khloe joining in the action.

She's over 6 months along with Tristan Thompson's baby, but still getting down.

Riddle us this -- if Kim, Khloe and Kourtney Kardashian all go to lunch in the rain, with two sisters expecting but only one of them pregnant ... who drives?

The question's gotta be asked, 'cause the 3 Kardashians found themselves in that exact situation Tuesday as they all grabbed some Italian in Woodland Hills.

It was pouring as they left, and while they certainly had their umbrella handlers -- they didn't have their own driver ... meaning 1 of these ladies got behind the wheel.

O.J. Simpson seems pretty convinced he's NOT Khloe Kardashian's real father -- and he's banking on you buying those two magic words ... "Trust me."

Juice finally addressed the conspiracy theory that's been floating around for decades ... that he secretly knocked up Kris behind Robert Kardashian's back 34 years ago -- and the family has been covering it up ever since.

So, when he was out in Vegas over the weekend -- a photog asked if congratulations were in order regarding Khloe's pregnancy.

Simpson clearly understood the subtext -- and replied, "Well, for Bob, God bless his soul, yeah. I don't know for me. I don't think for me I have nothing to do with it."

He added, "I would be proud ... but trust me, I had nothing to do with it."

Meanwhile, watch O.J.'s daughter, Arnelle, in the background -- she's CONVINCED her dad's no Kardashian creator.

Khloe Kardashian's first order of business when she got pregnant? Grab a hard hat!!!

Sources close to Khloe tell TMZ ... she had extravagant renovation plans for her Calabasas crib -- the one she bought from Justin Bieber in 2014 -- by turning a bedroom next to her master into a closet big enough for her massive clothes and shoe collection.

But, life happened. As TMZ first reported ... NBA superstar BF Tristan Thompson knocked up Khloe. So, that bedroom-turned-closet is going back to bedroom ... baby bedroom.

Khloe wants the baby's room as close to hers as possible, and that room's the perfect fit.

We're told Khloe is holding nothing back when it comes to the fine details of the room ... buying top of the line furnishings, decor and clothing.

Fetty Wap's baby mama is mostly out of the woods after giving birth 3 months early to a baby girl.

Alexis Skyy gave birth to Alayia, who has been placed in an incubator after reportedly weighing a little over 1 pound at birth. Alayia is stable according to The Shade Room. We're told Fetty was by Alexis' side the whole time and he's still with her at the hospital.

Alexis underwent a C-section after her water broke early Tuesday. She's reportedly also doing fine. This is Alexis' first baby and at least Fetty's fourth. He has 1 more on the way with a different baby mama.

Fetty, a premature baby himself, didn't seem worried based on the video they posted earlier this week.

"Fixer Upper" stars Chip and Joanna Gaines may have reason for concern over their unborn child ... and it centers around their ultrasound.

Joanna posted video of the ultrasound Wednesday after the couple announced they'd soon be welcoming their fifth kid. "Fixer Upper" fans speculated something was wrong with the images, because of excess fluid around the fetus. They've been commenting that the condition appears to mimic hydrops fetalis, a sometimes fatal condition.

Radiologist Nicole Saphier -- who has extensive experience in interpreting ultrasounds -- tells us there does appear to be skin edema (excess fluid in the skin). But Dr. Saphier is quick to add, although the ultrasound gives cause for concern, it's not conclusive. She says she'd need to see the whole ultrasound to determine if excess fluid is present in additional cavities such as the heart, lungs or abdomen.

French Montana clearly harbors no ill will or hard feelings after his breakup with Khloe Kardashian, because he couldn't be happier she's having a baby.

We got French Thursday night in West Hollywood at Poppy, and he didn't hesitate to express his joy over Khloe's pregnancy.

French and Khloe started dating in May 2014 and it lasted only a few months. It looks like he's starting to date Evelyn Lozada.

Khloe's due in early April.

Fetty Wap's baby mama, Alexis Skyy, is about to give birth any moment now ... even though she's 3 months early.

Alexis' water broke early Tuesday as she was seen being rolled in to a Georgia hospital with Fetty by her side. She's only 6-months pregnant at this point, so you'd think they'd be worried. If so ... Fetty didn't let on this video.

In fact, Fetty says he was a premature baby, too, and the kid's gonna be a soldier like her pops. They're expecting a girl, and Alexis has already been calling her Alaiya.

This will be at least baby #4 for Fetty, and he has 1 more on the way with a different baby mama. This will be Alexis' first.

"Fixer Upper" stars Chip and Joanna Gaines may have called it quits on their show ... but they're certainly not slowing down in the family department.

43-year-old Chip posted the photo Tuesday comparing his belly to pregnant 39-year-old Joanna's with the caption, "Gaines party of 7.. (If you’re still confused.. WE ARE PREGNANT)."

The duo announced they were calling it quits on their popular HGTV show back in September after 5 very successful seasons. In that announcement, they said, "It is with both sadness and expectation that we share the news that season 5 of Fixer Upper will be our last. While we are confident that this is the right choice for us, it has for sure not been an easy one to come to terms with."

Unclear if the soon-to-be Gaines family member had anything to do with ending the show.

Chip and Joanna already have 4 kids between the ages of 7 and 12.

Congrats!

8:30 AM PT -- Kim just thanked the doctors and nurses who helped Saint, saying, "I just want to thanks every nurse & doctor out there who works so hard around the clock. We are so grateful for you all!"

Kim Kardashian and Kanye West's son, Saint West, was hospitalized last week with a bad case of pneumonia ... TMZ has learned.

Sources tell us the 2-year-old was brought to an L.A. area hospital Thursday with pneumonia, and that his parents were with him while he remained hospitalized, sharing overnight duties.

We're told Saint was released on Saturday, so he was checked in for just a couple days. He's at home now, and sources say he's doing well.

Kim shared a family photo from Christmas just a few days before Saint was admitted.

Kim and Kanye also shared a New Year's Eve kiss on Sunday. The hospitalization went down right after her mid-week meet-up with J Lo and A-Rod -- where Kim and co. enjoyed a taco Wednesday party.

Good thing Saint's on the mend ... his new baby sis is supposed to be coming home sometime this month. She'll probably need her big bro to show her the ropes, sniffle free.

Kylie Jenner missed out on watching Travis Scott perform for New Year's Eve -- but she probably got a full report, 'cause she had a couple proxies there in her place.

Travis took the stage Sunday night at LIV nightclub presented by Monster in Miami, where some his baby mama's crew were in attendance. Kylie's friends, Justine Skye and Anastasia Karanikolaou, were seen dancing in the crowd, as was Kendall's gal pal, Hailey Baldwin.

Eyewitnesses tell us all three girls, and the groups they were with, ended up in the DJ booth together at one point in the night -- where Travis raged a bit himself though his set.

Preggo Kylie wasn't seen at LIV, which makes sense -- she's pretty far along as far as we know. And despite rumors she and Travis split, we're told they're still together.

Eva Longoria's comfortably embracing her 4-month-old baby bump to ring in the new year ... in PJs, no less.

The "Desperate Housewives" star posted her first public photo of her pregnant belly Monday with the caption ... "New year, new adventures! I’m so grateful to my beautiful family for giving this new baby so much love already! #HappyNewYear #2018."

As we reported ... Eva and her hubby, Jose Baston, are expecting their first child together -- which would be Eva's first baby ever. Her rep confirmed she's preggo with a boy.

Looks like the kid's gonna be welcomed with open arms. Congrats!

Kendall Jenner is NOT the 4th Kardashian who's expecting a bundle of joy -- she's just got a bun in the oven ... otherwise known as a bagel.

Kendall posted a mirror selfie Saturday and almost immediately had to respond to rumors that she was pregnant. Her slim figure looked a bit more hourglass-like in the pic, and people sorta lost their s***.

As it turns out, Kendall isn't preggo -- she's just fan of the doughy goodness that are bagels.

Pay attention, NBA dads -- Pistons guard Langston Galloway just set the big baller standard for gender reveals ... and teammate Andre Drummond's got the hilarious play-by-play.

It all went down at Little Caesar's Arena Tuesday night after the Pistons smashed the Pacers ... when Langston rocked the rim to figure out if he and his wife, Sabrina, are having a boy or girl.

Galloway killed it. The ball exploded, confetti went everywhere, and he and Sabrina hugged it out while his teammates cheered him on.

But the real MVP might have been Andre ... the unofficial emcee for Lang's ceremony.
