CELEBRITY JUSTICE ™

Twitter, Google and Facebook vigorously eradicate accounts created by terrorists networks ... the tech giants say in response to a lawsuit claiming they enable ISIS' terrorist activities.

TMZ broke the story ... a victim's father is holding the tech companies responsible for fueling the Paris attacks back in November, claiming the social networks make it easy to maintain accounts that promote ISIS' extremist propaganda.

A spokesperson for Twitter tells TMZ ... the lawsuit is without merit, adding they condemn acts of violence for which ISIS claims credit and actively work to eliminate any presence promoting terrorism.

Google tells us through a spokesperson, YouTube (which they own) terminates flagged accounts run by terrorist organizations. They declined further comment on the lawsuit.

3:10 PM PT -- Attorney Todd Wilson, the Kardashian/Jenner General Counsel, has released a statement in response to the lawsuit, claiming -- "APA's lawsuit is frivolous and the height of dishonesty. The Kardashians and Jenners terminated APA in March 2015 for being incompetent and breaching their fiduciary duties, which cost the Kardashians and Jenners hundreds of millions of dollars. Now the real story of how APA totally failed its clients will be told and APA will have to answer for its incompetence and wrongful acts."

The Kardashians and some Jenners made untold millions and aced out a company that did nothing but help ... so claims the company that is now suing the family.

Agency for the Performing Arts caters to huge brands like Marriott hotels and Lamborghini. They claim they had a verbal agreement in 2009 with Kim, Khloe, Kourtney, Kylie, Kendall, but no Rob -- to help make deals. The Agency was supposed to get a 15% cut.

APA says the Kardashians made millions after they locked deals for clothing, footwear, accessories, and hair products.

The suit claims the family pulled the plug on their deal back in March 2015, and since then the APA claims it hasn't seen a dime.

Twitter, Google and Facebook are responsible for the Paris attacks because they let ISIS spread extremist propaganda and recruit on their social networks ... so says a victim's father in a new suit.

According to legal docs obtained by TMZ, Reynaldo Gonzalez is suing the social media giants for enabling ISIS to explode into the most feared terrorist group in the world.

Reynaldo's daughter, Nohemi, was one of the 130 victims killed in coordinated attacks last November fueled by ISIS' ability to easily create and maintain accounts ... including on YouTube (owned by Google).

The family claims the social networks were negligent by allowing ISIS to post beheading videos. What's more ... the suit claims the tech giants raked in profits from ad placements in ISIS postings.

Reynaldo -- whose daughter was the lone American killed in the attacks -- says the social sites failed to take action despite outcry from the U.S. government.

In a move that shocked a South African courtroom, ex-Olympic sprinter Oscar Pistorius removed his prosthetic legs in court Wednesday -- and walked around on his stumps.

The guy who fought Justin Bieber last week wants a rematch, but no fists this time ... just a 1-on-1 chat about how they can avoid this turning into a lawsuit.

TMZ obtained a letter Lamont Richmond's rep fired off to Bieber's camp, saying Lamont wants a sit-down, and will take responsibility for the fight ... IF Justin does the same. Richmond adds, he thinks meeting face-to-face will "help seek a resolution."

It's unclear what needs to be resolved. The letter isn't any more specific, but the rep tells us if Justin's camp doesn't respond ... a lawsuit could be coming over the melee.

As we reported ... Lamont says he got death threats from Beliebers and lost his job after the fight.

Just a thought -- if Justin needs a bodyguard ...

Cops are virtually certain the Kardashians' clothing store was hit by a lone suspect, but his race is not nearly as certain ... based on the 911 audio we obtained.

A woman driving past the West Hollywood DASH store called in, describing the suspect as tall with a skateboard, throwing "something on fire." Check out the audio, there's a funny exchange about what that something was. However, the caller was sure the would-be fire starter was black with a baseball hat.

But hold off on that APB ... you gotta hear the second witness paint a much different picture. As TMZ first reported ... the store was targeted June 6 and there's still no suspect.

Kate Chastain -- the Chief Stewardess on Bravo's "Below Deck" -- was arrested after cops say she bit and choked out her girlfriend ... TMZ has learned.

Cops in Melbourne Beach, FL tells us Kate was booked Monday night after a domestic violence investigation launched when Kate's girlfriend's went to work with bruising on her arm.

According to cops ... Kate tried to kick her drunk girlfriend out of their house and when she refused, Kate bit her in the forearm, bicep and leg. Cops say Kate also put a knee on her head, choked her, and tried to stop her breathing.

Kate was arrested and booked for a felony domestic violence charge of battery by strangulation.

She appeared in court Tuesday afternoon ... and posted a $5,000 bond.

Kate's been featured on 2 seasons of "Below Deck" -- but the show was not shooting at the time of her arrest.

Kevin Hart got jacked of $500 grand when burglars broke into his house ... TMZ has learned.

Law enforcement sources tell us the backdoor to Hart's Tarzana home was pried open over the weekend while he and his family were gone.

We're told the thief or thieves made off with jewelry, watches and clothes.

Kevin -- who was in Miami training with Ndamukong Suh -- came home Monday and reported the theft.

We're told the house has surveillance cameras inside and out and cops are combing through video for a lead.

1:29 PM PT - Rose's lawyer, Maj Vasigh, tells us, "The charges were dropped in this case because, as both he and his wife have maintained from the beginning, Mr. Leppan was absolutely innocent. Mr. Leppan did not, nor would he ever hurt his wife or anyone else."

"Suspicion of domestic violence is a very serious matter, as it should be. Responding officers sometimes, even if unsure of what happened, make an arrest just to be on the safe side. That is what happened here; and after a careful look at totality of circumstances, the justice system came to the correct conclusion."

"Mr. and Mrs. Leppan both continue to be madly in love. And while no relationship is ever perfect, they are relieved that this very public personal experience is over."

Prosecutors have dropped the domestic violence case against WWE superstar Adam Rose ... after he proved he's getting professional help for his marital issues ... TMZ Sports has learned.

Amber Heard doesn't want Johnny Depp or anyone else thinking her domestic violence allegation is a play for his money -- and she's making that clear in court docs.

Amber's lawyer just filed a declaration saying she's withdrawing her request for temporary spousal support. The spousal support issue would have been handled during Friday's restraining order hearing ... but she's now taken that off the table.

Amber says she only asked for it because she thought it was standard operating procedure in a divorce case, but now feels Depp's team is twisting it in the media. In the docs, she says it's being "used against me to distract and divert the public away from the very serious real issue of domestic violence."

She claims Johnny made $30 million last year and, according to the docs ... she believes the court could have ordered him to pay nearly $1 million per month in temporary support.

Important to note -- Amber's not saying she doesn't want any support. In the docs, she reserves the right to go after spousal support in their divorce ... AFTER the restraining order is handled.

The Foo Fighters should have been fully covered when they pulled the plug on several concerts after terror threats, but Lloyd's of London is giving them the runaround ... according to a lawsuit.

The rockers filed the suit against Lloyd's for failing to pay up on a "terrorism" clause in their insurance policy. The band was scheduled to do shows in Turin, Italy on Nov. 14, 2015 and then Paris on Nov. 16 -- but the Paris terror attacks went down on Nov. 13.

The Foo Fighters cancelled both shows -- and two other European gigs -- out of safety concerns for themselves and fans. In addition, the day after the Paris attacks they say their tour website was hacked with images of an ISIS flag, an automatic weapon, and the chilling words, "Be prepared."

10:25 AM PT -- Mari turned herself into Airport court late Tuesday night. She was arrested and released a couple hours later.

'Love & Hip Hop' star Teairra Mari is learning a HARD lesson about punctuality -- you blow off a court case, the judge issues a bench warrant for your ass.

Here's the deal ... Mari was supposed to be in an L.A. courtroom on Monday to face charges that she beat the crap out of an Uber driver last year and stole his cell phone charger.

But when her case was called, Mari was MIA -- so the judge issued a warrant for her arrest.

Long story short ... Mari's been ordered to surrender to authorities so she can stand trial asap -- and if a cop spots her gallivanting around town, she could be cuffed on the spot.

Heavyweight boxing champ Deontay Wilder is suing the man he was SUPPOSED to fight back in May -- claiming Alexander Povetkin's positive doping test cost him MILLIONS ... and he wants his money.

In a lawsuit obtained by TMZ Sports, Wilder claims he was guaranteed 70% of the $7.15 MILLION purse for the May 21st fight (math translation: $5 million).

Problem is ... Povetkin tested positive for the banned substance meldonium (the same stuff Maria Sharapova was using) and the fight was called off 6 days before the bout.

Wilder says he was suspicious that Povetkin was doping since he had traveled to Spain in the months before the fight ... and "[Spain is] notorious as an epicenter of doping."

Amber Heard's camp just called the police ... claiming Johnny Depp's people are taking items from his downtown L.A. home in violation of the restraining order she has against him.

Law enforcement sources tell TMZ ... LAPD officers are responding to a possible violation of a court order. Johnny was ordered to stay 100 yards away from his home with Amber when she got the temporary restraining order.

Sources connected to the former couple tell us Johnny himself is not there, but his people are removing things from the walls and taking furniture out of the home.

Part of the restraining order includes a "move-out order" ... which allows Depp to take personal clothing and belongings needed until Friday's hearing. Amber's camp believes his people are overreaching, especially because Johnny is in the Bahamas right now. The insinuation is clear ... why the urgency?

Sources close to Depp confirm his team is taking "personal items" and they believe it's within the scope of what the order allows.

We got this shot of the moving truck loaded with a bunch of men's clothing, presumably Johnny's -- however, a desk was moved back inside the building. Law enforcement sources tells us both sides agreed it was not an essential item.

Leonardo DiCaprio's too busy jet-setting around the world to sit for a deposition ... at least according to the guy suing Martin Scorsese and Paramount for his portrayal in "The Wolf of Wall Street," -- and now he wants a judge to tell Leo he's gotta show up to get grilled.

According to legal docs, Andrew Greene, an ex-business partner of Jordan Belfort -- the real 'Wolf' -- says he'll fly to L.A. to meet with Leo if that's what the actor needs.

According to the letter, the studio's lawyers claim Leo's got a busy schedule and instead they've offered another witness -- an executive from the actor's production company.

Andrew's lawyers say that won't cut it, saying they've already deposed Scorsese, and the movie's screenwriter, Terence Winter. Now they want Leo.

Pittsburgh officials are hailing its citizens for celebrating the Stanley Cup "responsibly" Sunday night ... except for the one moron who was arrested for harassing a police horse.

The Pittsburgh Public Safety Dept. says ... for the most part, people celebrated responsibly -- no riots, no pepper spray, no major incident whatsoever.

But there was SOME stupidity.

Firefighters were sent to put out 2 couch fires and a mattress fire ... and cops responded to a 20-year-old male who was "taunting a Pennsylvania State Police horse."
