Baby Mama

Karrueche Tran was in the dark ... blindsided by Chris Brown's baby news just moments before TMZ broke the story.

We're told Tran had absolutely no idea her boyfriend was a daddy -- much less a daddy with a baby mama with whom SHE partied.

Our sources say Karrueche and Brown had a blowout fight a week ago and weren't speaking, but he tried calling her after the story broke ... she did not pick up.

DNA tests performed in the last week show conclusively ... Brown is the father of a 9-month-old baby with a former model named Nia. We're told he and Nia aren't romantic but they get along fine, and Chris has made some sort of financial arrangement with her.

As for Karrueche ... we're told she's actually relieved, because it now gives her a clean, permanent out.

Chris Brown had his cake and banged it too -- because months before he knocked up his baby mama ... he was partying with her AND Karrueche Tran at the same time.

Karrueche, who was Chris' gf at the time, actually had her arm around Nia in a photo they took -- with Christina Milian too -- during a Las Vegas party back in May 2013. Chris was also there.

Nia got pregnant with Chris' baby later that summer. We're guessing the ladies won't be having a reunion anytime soon.

We've also learned Nia was very popular on the video vixen scene ... appearing in several music videos, including a half-naked role in Phill Wade's "Dreams of You" video.

If nothing else ... Chris Brown was swimming in the right end of the gene pool when he knocked up his baby mama -- as evidenced by these pics.

As we told you ... the mother's name is Nia -- a 31-year-old from Texas who used to do some modeling, and she also appeared in music videos. We're guessing that's how she first hooked up with Chris years ago.

Chris Brown is the proud father of a 9-month-old baby girl ... TMZ has learned.

The baby's mother is a 31-year-old former model named Nia -- who we're told has known Chris for several years.

Sources connected to both Nia and Chris tell us they are on very good terms -- however they're not together romantically. We're told 25-year-old Chris is happy about being a father.

It does not appear there is a formal child support order in place -- and we do not know the nature of any informal terms of support.

One thing's for sure ... baby girl looks a lot like daddy.

Scooter Braun paid homage to Justin Bieber by giving his brand new kid the Biebs' initials.

TMZ has obtained the birth certificate for Jagger Joseph Braun … it can't be a coincidence that the kid's initials are JB and how could it be that Jagger is anything but Mick? In fact, the inspiration was indeed Mr. Rolling Stone himself.

The birth certificate doesn’t give the height and weight, but we are told that the baby is doing great and so is Scooter’s very hot wife, Yael Cohen.

As we reported Justin was one of the first people to visit the kid at Cedars-Sinai Medical Center where he was born.

Tyson ... Ali ... Rocky -- they've all got NOTHING on Hayden Panettiere ... or any other woman who's ever had to give birth ... so says Hayden's boxing superstar baby daddy Wladimir Klitschko.

Wlad says Hayden's pain tolerance must be through the roof in order for her to have pushed out their giant baby 2 months ago ... saying he now believes women are WAY tougher than any boxer.

"Every woman is a hero."

Hayden might be more of a hero than most ... considering their daughter Kaya was 7 lbs., 14 oz. and damn near 2 feet tall. Hayden's only 5 feet tall.

Ludacris' baby mama testified in court that it's ridiculously ludicrous he's fighting for full custody of their daughter, because he desperately wanted her to have an abortion to the point he even bribed her.

Tamika Fuller said when Luda found out she was pregnant he cried, but they weren't tears of joy. He said it would ruin his life and he then urged her to terminate the pregnancy.

According to Tamika, Luda initially offered her $10K and a house if she lost the baby.

As TMZ first reported, Fuller believes Luda's quicky marriage to Eudoxie was just a transparent ploy to show the judge he has a more stable home than her.

Ludacris' hastily arranged marriage is a cheap trick in his attempt to gain full custody of his daughter ... so says a source close to his baby mama.

We're told Luda's baby mama, Tamika Fuller, thinks Luda wants to show the judge in their custody fight that he now has a stable, loving household ... more conducive to child-rearing than the home of single mom Tamika. She fears a Georgia judge could actually buy what Luda's selling.

As we reported ... Luda abruptly proposed to GF Eudoxie during the XMAS holidays and married her the very same day. Tamika thinks it was all just a ploy.

Luda is gunning to win full custody of their 1-year-old daughter Cai. He claims he's a better parent and has the means to provide her with a better life.

Tamika thinks it's a crass ploy to avoid paying $7,000 a month in child support.

The courtroom fireworks begin later this month.

Hayden Panettiere can't escape the laws of physics -- birthing Wladimir Klitschko's baby did some permanent damage to her bod.

Hayden copped to the ordeal of bringing Kaya Evdokia into this world with People ... saying, "I'm limping around. I'm still trying to figure out what [pregnancy] has done to my body, how it's changed it."

As for recovery ... she added, "I know some things will never be the same again."

Sounds about right -- Kaya was 7 lbs., 14 oz. and damn near 2 feet tall. Hayden's only 5 feet tall.

Blake Lively doesn't need a sexy black dress for slimming effect -- 'cause even with a big ole bun in her oven ... she's a total smoke show.

The ex "Gossip Girl" flaunted her belly at a L'Oreal event in NYC last night ... creating a dilemma for all those fans who drooled over her bod long before Ryan Reynolds knocked her up about 5-6 months ago.

It's got to be Jennifer Aniston's worst nightmare ... another Angelina Jolie may be walking the face of the earth soon, because someone's in the market for an Angelina egg donor.

The UCLA Daily Bruin ran a classified ad Friday seeking an egg donor who looks like Brad Pitt's newly-minted wife.

The company that placed the ad -- Beverly Hills Egg Donation -- presumably has a client who wants their kid to be an outlier.

The ad is specific ... white, tall, slender, the right cheekbones and forehead. Anyone with the right stuff can make $30K for 2 cycles.

Beyonce tucked her ample frame into a tight one-piece bathing suit emblazoned with one of Jay-Z's most famous lyrics -- perfectly modified for her -- and then posted a photo for all to see.

Queen Bey has been blasted in the past for touching up her own photos, but this one appears to be undoctored ... or at least very well doctored. There is one obvious problem with the pic -- no ass shot in a pic where she's bragging about her ass.

Jason Patric just won a 2-year legal battle against his baby mama -- with a judge just declaring he is the legal father of 4-year-old Gus ... TMZ has learned.

Jason had a baby with ex-GF Danielle Schreiber, and after breaking up -- getting back together and breaking up again -- she fought hard against his bid to become the legal father, citing a quirky law.

According to the law ... if a man donates sperm to a woman to whom he is not married and a doctor facilitates the insemination ... the man has NO claim of custody or parental rights.

The trial judge ruled against Jason, he appealed and the appellate court said the trial judge was off base and sent it back for another hearing.

The second time was a charm for Jason. We've learned the trial judge just issued a sealed 45-page opinion ... concluding Jason is the legal father.

The judge ordered Jason, Danielle and their lawyers to try and hash out a custody, visitation and support agreement ... but if they can't, the judge will make the decisions.

This case became a rallying cry for father's rights -- and an enormous victory for Jason.

UPDATE: Schreiber's rep tells TMZ, "The proposed statement of decision is not intended to be public nor is it final."

David Arquette thinks he knows what it's like to breastfeed a baby ... and says it explains the nuclear meltdown with his fiancee in the middle of a West Hollywood street.

An angry Arquette was seen stomping away from celeb hotspot Craig's Friday night on foot ... with fiancee Christina McLarty in hot pursuit ... sobbing and begging him to come back.

On the video, Arquette can be heard saying, "I'm done. Just like your last guy." Some people took that to mean he was breaking off his 3-month engagement to McLarty, who gave birth to his son, Charlie, last April.

But David tells TMZ ... it was simply an argument between two exhausted new parents. The couple had a baby boy back in April and Arquette says, "We are both hormonal and haven't slept in 6 months. Christina is still breastfeeding, I feel like I am."

Fantasia Barrino says her baby daddy who is suing for custody of their teenage daughter is nothing but a deadbeat sperm donor.

Brandel Shouse claims in new legal docs he's a better parent than Barrino and he should be the primary parent for 13-year-old Zion. So he's gunning for physical and legal custody.

The former "American Idol" winner is incredulous ... claiming Shouse has NEVER had a relationship with or cared for Zion. She also says he's never given her a dime of financial support.

So Fantasia has decided if he wants to fight, then fight it is. Now she wants him to ante up child support. She says he's able bodied, employed and capable of earning substantial amounts of cash.

Mila Kunis and Ashton Kutcher just wrapped up their newest production -- in diapers -- Mila has given birth to a baby girl ... TMZ has learned.

Sources close to Mila's womb tell us ... Mila delivered Tuesday night at Cedars-Sinai -- the hospital of choice for many celebrities.

We're told they arrived at the hospital Tuesday around 6 A.M. ... and were taken right to a delivery room.

They came by themselves -- no entourage, no family.

Sources tell us Mila delivered right on schedule ... and delivered right around the Jewish New Year.

Mazel Tov!
