Kids

If you think you were pumped on Ronda Rousey's surprise Royal Rumble appearance ... peep this video of Travis Browne and her two stepchildren -- who had ZERO clue she had joined the company!!

Travis was PUMPED as soon as he heard Rousey's music hit ... but it took the boys, Kaleo and Keawe, a few seconds to figure out what was up.

Once they do ... their reaction is priceless.

Jesse Williams is firing back at his estranged wife, saying she's poisoning their children toward him ... and he insists she's all wet when she claims he has a girlfriend.

Aryn Drake-Lee has claimed Jesse is romantically involved with a woman the kids call Mama C. She claims it's in violation of their custody arrangement which requires them not to introduce a significant other until the relationship has lasted 6 months. He says she's a longtime mutual friend of theirs and that's it.

Jesse just filed legal docs saying Aryn has been interrogating their 2 children, trying to find fault with things he does.

She claimed in earlier docs his inconsistent schedule was disrupting their lives, hurting their development, but he calls BS, saying the kids eat their meals and get plenty of sleep while they're with him.

Jesse says it's rich for Aryn to complain about his work schedule, saying, "This is how I always supported our family and Aryn has no problem enjoying the financial benefits, including the $50,695 per month I pay her in temporary spousal support."

Chris Hemsworth's mini-me caught a clean wave Down Under worthy of a standing O.

Thor and his wife, Elsa Pataky, took their 3-year-old twin sons, Sasha and Tristan, to Byron Bay in Australia for surfing lessons. Sasha wasted no time proving he's destined for greatness in the water ... looking every bit like a pro with a low-center of gravity and perfect stance.

H-Town's Solomon "Shazam" Conner just got arrested, and it should teach him an important lesson -- if you're gonna knock boots, you better pay for the kids you might end up having.

Conner was busted Wednesday in Texas for failure to pay child support ... according to court docs. It's his second arrest for this. He and his twin brother founded the R&B group H-Town back in the '90s.

It's unclear how much Conner allegedly owes this time around -- but when he was arrested in 2015 for back child support, he'd racked up a $170k tab.

Jesse Williams' estranged wife has several new beefs with him -- the biggest being introducing the kids to his new girlfriend, and showing a complete lack of cupcake etiquette ... according to new legal docs.

First, the gf issues. Aryn Drake-Lee says the "Grey's Anatomy" star has been taking their 2 kids to his new chick's house since October -- and the kids even call her "Mama C." She also claims he took them on a mini-vacay to Big Bear Mtn. with the unnamed gf.

Aryn says this is a clear violation of the custody agreement which requires both of them to wait 6 months into a new relationship before introducing the children.

According to the docs, obtained by TMZ, Jesse also broke a golden rule at their daughter's school last month. Aryn says Jesse brought cupcakes to celebrate 4-year-old Sadie's birthday -- a big no-no because the school picks one day each month to celebrate all students' bdays together.

She claims Jesse also screwed her with Sadie. In the docs, Aryn says Sadie tearfully said "she was mad at me for not attending her birthday party" at school.

She says there are other issues ... mostly caused by Jesse's erratic schedule, and lack of notice before he picks up the kids. Aryn's asking the judge to set a more rigid and consistent schedule for his visits.

A source close to the former couple claims Aryn is making up lies because she's obsessed with being seen as a victim, and she can't do that if people see Jesse as the fun, caring, good person he is.

The Balls were all over the place in Lithuania on Tuesday ... with LaMelo and LiAngelo combining for a whoppin' 80 POINTS in LaVar's pro coaching debut.

BC Vytautas announced Papa Ball would join it's coaching staff for the 4th game of the Big Baller Brand Challenge against Alytaus Dzūkija ... and the strategy worked, 'cause he helped coach the team to a 147-142 win.

Not only did Melo drop 43 points (including 5 straight 3 pointers in the 3rd quarter and a fast break dunk), but Gelo added 37 of his own to secure the dub.

Tom Taylor -- the young actor who plays Jake in "The Dark Tower" -- got a nice payday for his work in the film, but the big bucks are (hopefully) yet to come ... TMZ has learned.

According to the 16-year-old's contract ... Tom banked $125k for his role in the movie alongside Idris Elba and Matthew McConaughey -- which is nice -- but will make double if he makes it into a sequel ... and $500k if there's a third installment. He'll also haul in $30k per episode if he lands the Jake role in a TV adaptation of Stephen King's story.

Here's the problem -- the movie massively disappointed critics after its summer release and reportedly barely broke even at the box office, taking in $111 million worldwide.

Since then, talk of a sequel's been muted, and even King has expressed concern about a TV project ... saying it would probably need to be a complete reboot.

Guess that's just show business, kid.

Kanye West has done so much for Chicago, naming his daughter after the Windy City is both awesome and deserving ... so says Common.

Common seemed both happy and entertained by his Chicago brethren's name choice for his third born when we got him Friday at LAX.

The name choice had mixed reviews, with one person on Twitter commenting Kanye naming his baby Chicago is the most Kanye thing to do ... but Common says 'Ye deserves the right for good reason.

Ewan McGregor has filed for divorce from his wife of 22 years.

Ewan cites irreconcilable differences as the reason he wants to end his marriage to Eve Mavrakis.

McGregor, repped by attorney Fahi Takesh Hallin, wants joint custody of the couple's 3 minor children. Eve, whose lawyer -- disso queen Laura Wasser -- filed her answer at the same time, is asking for sole physical custody with visitation going to Ewan.

McGregor says in the docs he's willing to pay spousal support. As for property ... our sources say there is no prenup so the assets should be evenly divided.

The date of separation is listed as May 28th of last year.

News of Ewan and Eve's split hit in October ... with reports saying the two had separated as early as May. The announcement came shortly after pics surfaced of Ewan kissing his "Fargo" co-star, Mary Elizabeth Winstead, at a London cafe.

Kim Kardashian and Kanye West chose a very unique name for baby #3 -- Chicago ... Kanye's hometown ... but it's a good bet she'll be known by a certain nickname.

Kim announced the name on her app by simply posting "Chicago West."

As we reported ... Kim and Kanye had their third child via surrogate, who gave birth Monday to a healthy girl weighing 7 lbs. 6 oz. Kim was in the delivery room during the birth, and we're told she was the first person to have skin-to-skin contact with the baby.

As you know, they already have 4-year-old North, and 2-year-old Saint. We're told the kids have been referring to her by the nickname Chi (pronounced Shy).

Welcome to the family, Chicago!!!

Kodak Black got busted after cops saw his infant child surrounded by drugs and a handgun during an Instagram Live broadcast.

As we reported, the rapper got arrested Thursday in Florida and was booked for 7 charges ... including drug possession, child neglect and grand theft of a firearm. According to police docs, obtained by TMZ, officers responded to Kodak's home after someone observed the IG vid of multiple men in a bathroom rolling joints and playing with a handgun.

Police say the final straw came when Kodak's kid was brought into the bathroom, and was just inches away from a lit joint, and the weapon. Police say Kodak did nothing to get the child away from the danger.

The IG Live broadcast was still rolling when police came into the house.

According to docs, police found weed out in plain view, and got a search warrant. They ended up finding 94.9 grams of marijuana in his bedroom closet.

Kris Jenner really is the super (rich) grandma we all wish we had ... 'cause she dropped close to $10k to make sure her 3 new grandkids will be strollin' in the dough.

Kris recently picked up 5 new pricey-as-hell baby strollers for Kim, Khloe and Kylie's kids -- all of which are valued at nearly $11,000 total ... even though she only spent around $8k.

Sources tell us Kris recently purchased 3 Silver Cross Balmoral Prams -- 2 black, 1 white -- at the Couture Kids baby store on Robertson Blvd. in WeHo, which cost $2,699 each. That's $8,097, if you're counting.

We're also told she was gifted 2 Silver Cross wave strollers, which normally cost $1,299 each. Sources say they were shipped out to Kris Thursday ... she put in her orders and requests at least 3 weeks ago.

As we reported ... Kris didn't skimp on baby gear for Kim's newest little girl. Looks like the other babies-to-come are getting the same treatment.

Kris Jenner doesn't scrimp on her grandkids, especially not for the newest Kardashian girl -- for whom she just dropped over $10,000 ... TMZ has learned.

Sources tell us Kris hit up baby boutique Petit Tresor in WeHo late last month and spent at least $10k on some pricey baby merch for Kim and Kanye's latest bundle of joy.

We're told Kris knew the baby would be due in January, so she wanted to get her order in early since a lot of this stuff is custom-made and would take a while to get delivered.

As for the order itself ... sources say Grandma Jenner bought a roughly $3,000 silver cross pram for kids -- which, we're told, was intended for North to push her new little sister around in. She also picked up a handcrafted Anaiza wooden crib for at least $6,000.

Last, but not least ... sources say Kris snapped up a bunch of custom baby outfits with rose applique for ALL of her grandkids at a couple hundred bucks each.

LaVar Ball was dead serious about starting his own semi-pro basketball league -- and now he's got the ball rolling when it comes to locking down the trademarks.

TMZ Sports has obtained documents showing LaVar (doing business as the Big Baller Brand) has filed applications with the U.S. Patent and Trademark Office to get the rights for the "JBA" aka the "Junior Basketball Association."

BBB is looking to use the league name and a logo (a silhouette of Lonzo Ball dunking) for athletic apparel, uniforms, hats, footwear, etc.

LaVar has previously said he wants to create the league for high school basketball players who don't want to play for free in college ... but can't get to the NBA yet.

He's stated he wants to pay players between $3,000 and $10,000 per month. He's looking to recruit 80 players to fill 10 teams.

LaVar is gunning to launch the JBA in the Summer of 2018.

UFC pound-for-pound king Demetrious Johnson says it's "an honor" Anderson Silva called him the greatest fighter of all time -- but tells TMZ Sports he does NOT think he's G.O.A.T. status.

That said, when the guys on "TMZ Sports" (airs weeknights on FS1) really pressed the flyweight champ for an answer -- he did admit he's getting close.

"I don't believe that," Demetrious told us ... before adding, "I do believe that I have, out of all the champions and all the opposition I've fought ... it's getting there."

FYI -- Mighty Mouse recently broke Anderson's UFC title defense record with his 11th straight ... but dude might be too humble to ever say he's the best.

John Stamos ain't got daddy issues ... never mind he's gonna be a first-time papa.

We got the "Full House" star at LAX with his pregnant fiancée, Caitlin McHugh, in tow and wondered what it'll be like to a first-time father at 54. Our photog might've touched a nerve there, so he pivoted and then asked ... if his TV dad skills will translate in real life.

John cracked a joke, but the future DILF revealed he's actually really great around babies.
