Baby Watch

Beyonce is pregnant with not one but 2 ... she and Jay Z are having twins.

35-year-old Bey just posted on her Instagram account, "We would like to share our love and happiness. We have been blessed 2 times over. We are incredibly grateful that our family will be growing by 2, and we thank you for your well wishes. -- The Carters."

So, 5-year-old Blue Ivy will have a brother and sister, 2 brothers, 2 sisters or something like that.

Beyonce's pregnancy announcement was news to some of the top dogs at AEG Live ... the company that is producing Coachella.

Sources connected with AEG Live tell us ... at least some of the top execs had no idea Bey was expecting, and it now makes her headlining gig at the festival problematic.

It seems Beyonce is somewhere in the vicinity of 4, maybe 5 months pregnant. Coachella is slated for April, so she'll be well along and obviously very big, given she's having twins.

One of our sources joked -- at least we think it's a joke -- "The show will go on. She'll just borrow Dave Grohl's big chair," the one he used when he broke his foot. It worked for Axl Rose at Coachella.

Doesn't matter that he's a world-class swimmer ... Ryan Lochte says there's no way in hell he's allowing his fiancee to have a water birth when their kid is born.

Lochte and his fiancee, Kayla Rae Reid, announced their pregnancy back in December -- and Kayla says she seriously looked in to having a live water birth.

But Lochte says he shut that down real quick -- explaining he wants his son born in a hospital with the proper resources to help his family in case anything goes wrong during the birth.

The actress set to play Wonder Woman on the big screen doesn't know a couple of things -- the sex of her new baby ... or the true meaning of show business.

We got "Wonder Woman" star Gal Gadot Monday heading to Fred Segal in L.A. -- where she seems to be hiding her baby bump -- and while she definitely plays coy to our first question ... she has a genuine deer in the headlights response to our second.

More drama in the Reggie Bush alleged baby scandal ... the woman claiming to be his mistress is MARRIED and now her husband wants out.

As we previously reported, a Miami nightclub waitress named Monique claims Bush (who is also married) sperminated her last year and approached him about child support. The baby is due in February.

Now, we've learned Monique was married at the time of the alleged tryst -- and her husband is PISSED. He's filed for divorce and it's clear from the docs he's convinced Bush is the father of her unborn kid.

He's named Bush several times in his divorce papers and is demanding she hand over any documentation proving he could be the father ... such as DNA tests, confidentiality agreements or payments he may have made to her.

The husband also notes he didn't have sex with his wife around the time of conception -- so there's no way HE could be the daddy.

A rep for Bush had previously called the baby allegations "rumors" and noted he's still "happily married."

We've also learned a lawyer for the husband reached out to Reggie's camp to try work out a private deal to keep the NFL star's name out of the court papers. Obviously, no deal was reached.

Just days after that rough loss to the ATL Falcons, Russell Wilson popped up in Beverly Hills ... where he got to spend some quality time with his wife and fetus!

The couple was spotted out on a breakfast run early Tuesday morning -- Ciara in a tight dress to show off her bump.

She's in her 3rd trimester. The kid is due around the end of March.

Cuteness all around ... just one piece of advice -- CARRY THE BAG, BRO!

Talk about a crazy reversal of emotions ... hours after the Cowboys' devastating lost to the Packers, Dallas' stud wideout Cole Beasley had a baby!!

We're told Beasley's wife, Krystin, gave birth to a bouncing baby boy in the wee hours of Monday morning and the entire family is stoked!

The kid is happy, healthy and Krystin is doing well.

Cole tweeted about the birth Monday morning saying, "The only thing that could heal me has arrived. I love my family so much."

J.R. Smith's newborn daughter is continuing to fight hard after her premature birth and we're told she's doing well ... TMZ Sports has learned.

The Cleveland Cavs star and his wife, Jewel, announced their daughter, Dakota, was born 5 months premature earlier this month.

Now, we're told specifically Dakota was born between 21 and 22 gestational weeks. She weighed roughly 1 pound at birth. A typical healthy pregnancy is 40 weeks.

Obviously, Dakota -- who's now 8 days into her battle -- is receiving the best care possible.

There are reports from around the world of babies born that early who survive. It's rare. They've been described as "medical miracles." Here's hoping Dakota can be one of those miracles.

Ashton Kutcher and Mila Kunis now have 2 kiddos hanging off their arms ... and they couldn't look any happier for it.

Paps got the couple grabbing breakfast Sunday morning in L.A. with their kids in tow -- 2-year-old Wyatt held hands with mom ... and newborn Dimitri got cradled by his pops.

Kids ... what a joy.

Natalie Portman is a trooper ... lugging bags along the street when she's clearly on birth watch.

We got Natalie out and about in Los Feliz Friday, carting her cache from a local bookstore.

It will be the second child for Natalie and hubby Benjamin Millepied.

Can't wait for the birth ... to be honest partly because she's such an awesome actress and we want her back.

Preggo Jenelle Evans and her current baby daddy, David Eason, headed to a custody hearing Wednesday in North Carolina over her 2-year-old son with ex-fiance, Nathan Griffith.

Not at all awkward.

The "Teen Mom 2" star is expecting a girl at the end of the month with Eason. Hopefully her drink was decaf.

Janet Jackson is a mom for the first time.

Janet delivered a baby boy Tuesday with hubby Wissam Al Mana, and the kid's name is Eissa Al Mana ... according to Janet's reps.

Remember, Janet unexpectedly postponed her Unbreakable World Tour last year to start "planning our family" ... as she put it in a video message to disappointed fans.

People was the first to report the birth. JJ's reps tell us the 50-year-old singer had a "stress free healthy delivery."

Congrats to Janet, and also to her fans ... anxious for her to continue the tour.

Pink and Carey Hart have shown supreme allegiance to their favorite whisky, by naming their new baby Jameson.

TMZ obtained a copy of the birth certificate, making Jameson Moon Hart official.

The kid was born the day after Xmas at Cedars-Sinai Medical Center in L.A.

And of course there's a Kardashian connection. The doc who delivered the baby boy is Paul Crane, the OB/GYN of choice for the Kardashian women. We also reported he just delivered Zach Galifianakis' kid.

Zach Galifianakis' newest baby boy will be forever tied at the belly button to the Kardashians ... since his pops used Kim, Kourtney and Kris' same OB/GYN.

Zach's son, Rufus Emmanuel Lundberg, was delivered by none other than Dr. Paul Crane, who also delivered all the Kardashian babies as of late ... including Dream.

According to the birth certificate -- obtained by TMZ -- Rufus was born on Nov. 7 this year at Cedars-Sinai Medical Center to his parents Zach and Quinn Lundberg.

It's strange ... Zach and Quinn have been married since 2012, but Rufus bears his mother's surname for some reason. Maybe Galifianakis was too much of a mouthful -- heck, maybe Kardashian would be more appropriate.

Tristan Thompson may have hit a speedbump on his way to fatherhood ... he isn't named on his new son's birth certificate.

Tristan's ex, Jordan Craig, gave birth to their son on Dec. 12th in L.A. -- and while she (obviously) lists herself as the mother, the space for the other parent is left blank.

What's interesting is their son, Prince, has the last name "Thompson."

So, what does it mean? In California, the father has to be present at the hospital in order to be named on the initial birth certificate. However, it's possible to add the name later.

Kobe Bryant has a NEW Christmas Day tradition -- one that doesn't involve basketball -- and it seems his wife, Vanessa, couldn't be more excited about it!

FYI, Kobe spent 16 of his last 20 Dec. 25ths playing in the NBA's Xmas day classic -- and became the #1 all-time Xmas day scorer with 395 total points.

But that was before he retired ... because this year it was all about his new baby, Bianka -- and Macaulay Culkin!

In fact, Vanessa seemed PUMPED about her new holiday plans when she posed about it on Instagram ... saying, "No more games on Christmas. 🏀 🎶"For the first time in forever..........."- (Princess Elsa voice)🎶❄️❄️❄️ #PeacefulHoliday #Christmas #FamilyTime 🎁🎅🏽🎄#HomeAlone2."

Kobe also posted, "Home watching a classic and realized this was my face 1 week ago when I realized I didn't have the NBA package LOL #mindblown."

Welcome to your new life, #24.
