Baby Watch

Being 35 weeks pregnant ain't gonna stop Serena Williams from gettin' her sweat on ... 'cause the tennis superstar is still killiin' it in the gym during her 3rd trimester!!

Williams -- who announced she was 20 weeks pregnant back in mid-April -- hasn't slowed down one bit with a bun in the oven ... playing preggo tennis and posing naked for the cover of Vanity Fair.

Serena told TMZ Sports in May that she's not gonna retire once she gives birth -- and her mom says she's gunning to return to the court as soon as possible.

G.O.A.T.

The baby business is BOOMIN' for Antonio Brown -- his girlfriend just gave birth to their brand new son!

The Pittsburgh Steelers wide receiver was able to get away from football Tuesday for the birth of Apollo Brown!

(It helps that today was a scheduled off day for Steelers players!)

Both baby and daddy looked great (Antonio had a big smile on his face) -- hopefully mom, Chelsie Kyriss, is doing well too.

It's AB's 5th kid -- 3 with Chelsie and 2 from a previous relationship.

George and Amal Clooney are ready to defend their infant twins in court ... as they vow to sue a French magazine that published pics of them.

The mag, "Voici," published shots on Friday of the Clooneys cradling Alexander and Ella. They appeared to be in a backyard, and George says that's exactly what happened ... and he's pissed.

In a statement he says, "Over the last week photographers from Voici magazine scaled our fence, climbed our tree and illegally took pictures of our infants inside our home. Make no mistake the photographers, the agency and the magazine will be prosecuted to the full extent of the law."

Assuming it went down as George said ... he's got a strong case. Under French law, public figures -- like George -- can only be photographed while going about their public lives ... and only for journalistic purposes.

Even in Italy -- where George and Amal were in the photos -- photogs cannot peep into a private residence or take photos of people or objects hidden from normal visibility.

George says, "The safety of our children demands" he go forward with a lawsuit.

The magazine responded saying the pictures published "are a response to a public demand" and that the pictures "do not put in danger Mr. Clooney, his wife or their kids."

Kevin Hart and his pregnant wife look to be rock solid ... on the sand down in Cabo San Lucas.

Eniko's about six months along right now and still rocking a bikini during their Mexican beach vacay. She and Kevin showed no signs of tension the week after cheating allegations were reported. Kevin's dismissed that as "BS" ... btw.

The Harts were hanging with Ludacris and his wife, along with several other friends -- and the guys were flexing and mugging around the pool.

Jessica Alba's got her third bun in the oven ... and she's making sure it gets plenty of sun.

Alba's currently enjoying summer in Hawaii on the heels of news she's having another kid. She's already mom to 2 daughters -- 9-year-old Honor and 5-year-old Haven -- with husband Cash Warren.

Jessica Alba's now tanning for 2 ... and has no problem flaunting it either.

The actress put her baby bump on full display as she lounged at the beach in Hawaii Tuesday. Alba's on a babymoon getaway after announcing Monday she's expecting her third child with husband, Cash Warren.

Although she's a mom these days, and expecting another, ya can't see Jessica sunbathing without reminiscing about her most famous beach pose ... from more than a decade ago.

It really is like a fine wine.

Now we know ... Rumi Carter is the big sis and Sir is the little bro -- their birth certificates reveal when and how they came into the world.

TMZ obtained the docs for Beyonce and Jay-Z's twins, and it nails down their delivery date and time -- June 13 at 5:13 AM. Rumi came out first, and Sir followed shortly thereafter.

What's really interesting is the doctor who pulled off the delivery -- none other than Dr. Paul Crane. The same guy who delivered Kim and Kourtney Kardashian's 5 kids ... and Rob and Blac Chyna's little girl, Dream.

It's been kinda obvious for awhile, but now we know for sure -- Cristiano Ronaldo's hot model girlfriend is preggers!!

The soccer superstar confirmed the news in an interview with El Mundo Tuesday ... when he was asked if he was happy about his GF Georgina Rodriguez's pregnancy.

His answer: "Yes, very much."

Georgina's been sporting a baby bump for months, FYI.

It's gonna be kid #4 for Ronaldo ... who introduced his surrogate twin babies, Eva and Mateo, last month. CR7's also got a 7-year-old boy from a previous relationship.

Irina Shayk and Bradley Cooper's baby girl is showing off her genes.

While Bradley was taking in Roger Federer's Wimbeldon victory, Irina and 4-month-old Lea de Seine got in their own sports action in L.A. with a hike. Well, Mom did the hiking, Lea was just the super cute window dressing.

This is our first glimpse of the infant, and can't say we're too surprised at her adorableness. As they say ... consider the source.

Beyonce and Jay-Z's twins are finally camera-ready and making their public debut.

Sir and Rumi Carter posed with Mom surrounded by a rose-filled trellis in an oceanside location -- it looks a lot like the grounds of the Malibu palace where we know Bey and Jay have been living since the kids were born.

It's been about a month since the little boy and girl arrived. As we first reported ... they were hospitalized for a while after birth to get treatment for jaundice.

Not only do they look totally healthy now ... check out the full head of hair on one of 'em!

Congrats!

Fatherhood's been kind to George Clooney so far ... as in he doesn't look stressed, sleep-deprived or like he's put on a few extra new daddy lbs.

George and Amal were out having dinner with friends Tuesday on Lake Como, Italy and they're the poster children ... for pissing off all other new parents of twins. The Clooneys were without Elle and Alexander and seemed vibrant and well rested.

George is tan with a fresh goatee, while Amal was glowing and smiling ear to ear. Not a bag under either of their eyes.

Still no peek at the little ones -- the twins were under cover upon arrival in Milan -- so looking at Mom and Dad will have to do. Bellissimo!

Jason Kidd could have a new nickname -- Octodad -- 'cause the Milwaukee Bucks coach's ex-wife says he's expecting his 8th child!!

We spoke with Joumana Kidd outside Delilah in West Hollywood -- where the TV host broke the baby news to TMZ Sports ... and said she couldn't be happier for J and his wife, Porschla.

Kidd's oldest son -- Jason Kidd Jr. -- was also out that night (in more ways than one) ... telling TMZ Sports he's just wants to keep the crown as the "gay son" in the family.

It's the first time Kidd Jr.'s gone public with his sexuality -- and told us in a statement, "My sexuality doesn't change me, it only makes me the pink glittery sheep of the family. And I own it."

We reached out to Kidd about the baby news -- but so far, no word back.

When your father's a mega-rich tequila baron, you fly to Italy on a private jet ... even when you're just 1 month old!!!

That's how George and Amal Clooney rolled this week ... touching down at an airport Monday in Milan on a sick PJ, with babies Elle and Alexander getting the total VIP treatment.

The kiddos -- born on June 6 in London -- each got their very own bassinet. George carried one, Amal got help carrying the other.

It's been a pretty good year for the Clooneys -- besides the twins, George's Casamigos tequila company sold for $1 BILLION back in June.

Welcome to the good life, kids.

Janet Jackson's estranged husband looks like he has a go-to spot to hang with their baby boy, and he knows just where to park it.

Wissam Al Mana was holding baby Eissa Monday in London on a park bench -- one he appears to frequent with his kid.

As we reported ... Janet and Wissam split back in April and are in the throes of a divorce. Their son was born just a few months before the separation.

Robert Griffin III is a proud papa for a second time ... his fiance just announced the birth of their daughter.

Grete Sadeiko announced Tuesday she gave birth to Gloria who was born Sunday and came in at a healthy 6 pounds, 12 ounces.

Grete wrote on Instagram, "Couldn't have done it without this man by my side, my backbone. Trying to make me laugh every way possible and keeping me entertained through all the pain and doing everything to make me smile and get through this. You deserve a medal baby!"

The NFL and Florida State track star got engaged back in May ... on the same day she announced she was preggo with Robert's kid.

Chief Keef's taking paternity cases to a new level -- the rapper's been named the daddy without ever taking a DNA test.

According to docs obtained by TMZ, a judge went all Maury by declaring Keef is the father because he never responded or objected to the case. The baby mama is former porn actress, Aareon "Slim Danger" Clark, who gave birth to a baby boy, Zinc Clark, last July.

Zinc's already got baby locks! Dad must be proud.

Slim tells us Keef's never seen the kid, and never took a paternity test ... which is why she took him to court. Zinc is 21-year-old Keef's fourth child.

We've reached out to Chief Keef, but no word back. Must be out buying cigars.
