Saatchi has been hounded by the U.K. media ever since photos surfaced showing the ad mogul getting a little too hands on with his celebrity chef wife Nigella Lawson.
But today, Saatchi arrived solo to the the swanky 34 Restaurant in London.
With Lawson reportedly out of town -- and far from Saatchi's grip -- looks like the only thing he'll be choking in the near future is his own chicken.
The woman behind the lawsuit is Katie Summers -- real name Katherine Howard -- who claims she was paid to appear in the film back in 2009 ... and the role involved sexual interaction with John Stagliano (aka Buttman).
In Katie's lawsuit, filed in L.A. County Superior Court and obtained by TMZ, the porn star claims Stagliano had known he was HIV positive since 1997 ... but failed to disclose that information before they shot their sex scenes for the movie.
FYI -- Stagliano has been open about his condition for years.
Still, Katie claims she didn't find out about Stagliano's condition until 2012 ... 3 years after they shot the movie.
In her suit, Summers does not say if she is HIV positive.
Summers is suing for negligence, intentional infliction of emotional distress and sexual battery. She's also suing John's production company -- Evil Angel Productions -- which produced the flick.
Summers is suing for unspecified damages -- and wants a judge to hit Evil Angel with an injunction forbidding the company from continuing to produce movies with Stagliano unless it discloses his condition to others.
Mary J. Blige is being sued for allegedly bailing on a concert in Dallas last December -- and according to the lawsuit, it's kinda Mick Jagger's fault.
A promotional company called Vision Entertainment Worldwide has sued Mary J. and her production company, claiming the singer agreed to perform in Dallas on December 9th, 2012 ... but canceled just a few days beforehand.
VEW claims it paid Mary a $145,000 deposit to appear ... and she never paid back the money, despite pulling the plug on the show.
VEW claims Blige blew them off because she got a better opportunity to perform at the Barclays Center with Mick Jagger and the Rolling Stones on December 8th ... and she took it.
VEW is now suing for breach of contract and more -- demanding at least $145,000 in damages. Calls to Blige's camp haven't been returned.
Sources tell us, Stahl -- who has long struggled with drugs, alcohol, and other personal issues -- was transported to the medical facility around 3:30 AM this morning by a friend ... it's unclear why.
Details about circumstances of the psychiatric hold are also unclear.
It's a huge bummer ... we spoke to Stahl just last month, and he told us he was finally focused on turning his life around.
49ers QB Colin Kaepernick is totally jacked up for next season -- after losing the Super Bowl this year -- showing off his beefy man arms in a black tank top today during a sunny stroll in L.A.
Good thing the shirt's got plenty of neck room. Wouldn't wanna choke ...
Charlie Sheen has told "Anger Management" producers -- FIRE SELMA BLAIR ASAP OR ELSE HE'S QUITTING THE SHOW ... TMZ has learned.
We broke the story -- Charlie has been on a mission to get Selma 86'd from the show because he believes she's been complaining about him behind his back ... trashing his work ethic.
Now, sources tell TMZ ... Charlie returned to work Monday and told producers he wants the termination process started TODAY ... or else he'll walk.
It's a big threat from Charlie -- who's set to make between $75 and $200 MILLION if he completes the 100 episode order for "Anger Management" ... depending on how it does in syndication. We're told Charlie's completed roughly half of the 100 episode order.
We're told Charlie understands that there can be complications with firing someone from a TV show ... but he wants producers to begin drawing up an exit strategy for Blair by the end of the day.
Sources connected to the production tell us ... Selma was not on set yesterday, though it's unclear if she was scheduled to work.
This morning, Blair was spotted out on a walk with her kid -- and when asked about her potential termination from "Anger" she just shook her head and replied, "I don't know anything."
We're told FX network execs are currently in talks about how to handle the situation ... but it's unclear if Blair's fate has been decided.
After days of ridicule, Miss Utah finally had a chance to redeem herself on the "Today" show this AM -- and this time she answered the infamous pageant question WITH FLYING COLORS!!! For a beauty queen.
Marissa Powell sat down with Matt Lauer and explained -- as TMZ previously reported -- that nerves got the best of her during Sunday night's Miss USA contest ... causing her to give one of the most confusing answers in pageant history.
Matt, being the saint he is, gave Marissa ONE MORE SHOT to get the question right ... see how she did this time. And remember folks she only had 48 hours, the Internet and a team of people to help her prepare.
Talk about pressure.
Rapper J. Cole was extorted by a sick fan who tweeted a photo of a little girl with a gun to her head ... and claimed he would shoot her if Cole did not respond to his message.
The fan tweeted last night "@JColeNC retweet me and I'll buy Born Sinner. Don't retweet me and I'll kill my lil sister."
Shortly after the threatening tweet, which refers to Cole's new album ... Cole did indeed retweet the message.
It's unclear if the gun is real or where the twisted bastard behind the tweet actually lives. The account, which we're not revealing, claims to be out of Saudi Arabia -- but the truth is it could be anywhere in the world.
We reached out to police in North Carolina -- where J. Cole lives -- to see if they were investigating ... but they hadn't heard anything about it.
We also contacted Twitter headquarters ... a rep said the company doesn't comment on individual accounts to protect privacy
This morning J. Cole commented about the incident, saying ... "Wildest s**t I ever seen on twitter."
11:15 AM PT The fan is now downplaying his tweet by claiming it's a BB gun in the photo -- apparently, oblivious to the fact even a BB gun could seriously harm a child at that range.
Law enforcement sources tell TMZ, private security guards near Rihanna's Pacific Palisades property called police just after 10 PM, reporting they had detained the 26-year-old alleged trespasser. Guards then held the man until officers arrived, and turned him over. The man was subsequently placed under arrest.
We're told the man was adamant ... he did NOT know it was Rihanna's house he was creeping around -- though cops tell us he had a Google map of the area pulled up on his phone. (Maybe he just got really lost???)
Bail was set $2,882. He's still in custody.
According to the L.A. Times -- which broke the story -- Rihanna wasn't home at the time ... she's in the U.K. on her Diamonds World Tour.
It's been a wild year for Rihanna's L.A. pad -- she was swatted in April ... and there was also that guy who tried to break into her house and sleep in her bed. The perks of being famous.
Wayne just tweeted about his controversial video shoot for "God Bless Amerika" in New Orleans ... saying, "I didn't step on the flag on purpose! It's a scene in a video where the flag drops behind me and after it drop it's just there as I perform."
Translation -- I swear it was an accident ... please don't hate me.
So ... you buyin' Weezy's explanation?
Advertising mogul Charles Saatchi -- one of the biggest art collectors in the world -- was given an official "caution" by London police after photos emerged showing the 70-year-old CHOKING HIS WIFE with his bare hands.
The story is exploding in the U.K. ... after photos surfaced showing Saatchi with his hands wrapped tightly around the neck of his wife Nigella Lawson -- a celebrity chef who recently appeared on "The Taste."
The photos were taken while Saatchi and Lawson were having dinner last week at Scott’s in Mayfair -- a very posh London restaurant.
Saatchi insisted he wasn't trying to hurt Lawson -- claiming they were merely in the middle of a "playful tiff." The look of sheer terror on Lawson's face says otherwise ...
Saatchi also said, "The pictures are horrific but give a far more drastic and violent impression of what took place. Nigella’s tears were because we both hate arguing, not because she had been hurt."
Lawson has reportedly left the couple's home with her children -- though Saatchi insists he sent her away to escape the media blitz until "the dust settled."
Les had his own table at the award show Sunday night ... where he watched disaster after disaster unfold on the stage ... culminating with producers giving Aisha Tyler the WRONG ENVELOPE to open during the Best Talk Show presentation.

But there was a silver lining for Mr. Moonves -- check out the video to see why Les was THRILLED after the show.
Justin Bieber was under investigation for a possible hit and run accident involving a paparazzo overnight -- but police have now cleared him of any wrongdoing ... TMZ has learned.
Justin was leaving the Laugh Factory on Sunset Boulevard around 11:45 PM in his infamous white Ferrari. His pal Lil Twist was there as a passenger, and several paps were on scene shooting the duo.
Once Justin got behind the wheel he motioned for some of the photogs to clear out of the way -- but when he drove off he appeared to pin one of them between the Ferrari and a parked car.
Justin did not stop.
LAPD launched an investigation and interviewed Justin a few hours after the incident ... and he told cops he didn't know he hit the photographer (not a TMZ employee).
Police say the photog was not seriously hurt, but was at fault because he was a pedestrian in the roadway.
So, Justin's in the clear ... this time.
