X-Factor

No fetus is gonna slow Simon Cowell's roll -- the "X Factor" judge is still partying his ass off on a yacht in the French Riviera ... with bikini-clad women ... while his pregnant baby mama is waging her divorce war back in New York.

A shirtless Simon and his mystery blonde were photographed just hours ago, soaking up the rays on France's Mediterranean coast ... not a care in the world.

Meanwhile, Simon's baby mama Lauren Silverman is toughing out nasty divorce proceedings with her estranged husband.

Simon Cowell is upset ... very upset he's in the middle of what is becoming a bitter divorce between Andrew Silverman and Simon's soon-to-be baby mama Lauren Silverman, and he's pressuring her to settle ... sources with direct knowledge of the situation tell TMZ.

We're told Simon HATES the bad publicity, which he feels is making him look like an underhanded cad. Our sources say Simon has painted a clear picture to Lauren -- the money she'll get from Andrew is minimal because of their prenup, so any significant cash will come from Mr. X Factor himself.

We're told Lauren is nervous and doesn't want to upset Simon, so she's feeling the heat. Her problem -- she and Andrew are at odds over custody of their 7-year-old son, and she feels she may have to give too much in order to end things and appease Simon.

Although both sides have said they want to resolve the divorce amicably for the sake of their kids, we can tell you there's a lot of bad blood on both sides and it's getting really nasty.

Andrew Silverman is PISSED after reading the TMZ post Saturday, in which close friends of Lauren told us she's upset at allegations she cheated on him ... because she says he knew about her relationship with Simon Cowell from the get go.

A close friend of the couple tells TMZ ... the notion that Andrew knew about the relationship is ridiculous, adding "She knows this isn't true."

Another thing that pissed Andrew off ... that sources told us Lauren was upset at stones being cast at her because Andrew partied with girls all over the world (though she never used the word "cheating.").

Andrew's friend tells us Andrew says it sounds like "a desperate attempt to smear him."

And the plot thickens. Lauren's lawyer fired off an email to us, saying a lot of the comments attributed to his client are inaccurate, though he doesn't specify which. He also says Lauren and Andrew are trying to settle the divorce privately.

As for Andrew ... the friend says "The two of them have been spending time trying to sort it out and keep things as normal as possible for the kid and this doesn't help."

Simon Cowell is in plenty of hot water ... which is what happens when you bang your friends wife and knock her up. Now Andrew Silverman is fighting Lauren for custody of their kid in a bitter divorce. So we gotta ask ...

UPDATE: We got an email from Lauren's lawyer, saying "Many of the statements [in our story] are simply inaccurate," though he does not specify which. He adds the parties are trying to settle the case confidentially, on a "private basis."
---------------------------
Lauren Silverman -- the woman who is pregnant with Simon Cowell's baby -- is telling close friends she is outraged at her estranged husband's "shock" that Simon was banging her ... because she says he knew what was going on the whole time and he was doing the same thing.

Sources close to Lauren tell TMZ ... Lauren is bitching that she hooked up with Simon partly because her estranged husband Andrew Silverman was cavorting around the world and partying with girls on various continents.

What's more ... Lauren is telling her friends her relationship with Simon evolved right in front of Andrew and he never said he had a problem with it -- it was a tacit mutual understanding.

Lauren is saying she would speak to Simon several times a day on the telephone and Andrew knew they were talking.

Lauren says she visited Simon in England several times and Andrew had no problem with the trips -- and it was obvious what was going on.

Lauren is beyond pissed that Andrew is now feigning shock, because she says he knew everything from the get go.

As for their divorce, Lauren is telling friends, there are no real money issues. The real sticking point is their 7-year-old son. Andrew wants full custody but Lauren is saying no way in hell will he get that.

Simon Cowell's ex-fiancée is doing something rarely seen in Hollywood -- treating his baby news like a bonafide adult because she's actually HAPPY for him ... sources tell TMZ.

After news broke Cowell knocked up Lauren Silverman ... it was reported that his ex-fiancée of two years Mezhgan Hussainy was devastated, thinking it should have been her.

Sources close to Mezhgan tell us, that couldn't be further from the truth. She and Simon have remained close since their split -- they're good friends and talk almost every day.

In fact, Simon told Mezhgan about the baby weeks ago -- and she immediately called Lauren, who she's also friends with, to offer her congrats and support ... knowing how stressful the media attention can be.

Bottom line: she's thrilled for the couple. As long as Simon's happy, she's happy.

The friend Simon Cowell betrayed wants out of his marriage STAT ... because he thinks his wife is a starf**ker who doesn't need any money from him because she'll get a ton of cash from Simon ... sources close to the couple tell TMZ.

Our sources say Andrew Silverman is gunning for primary custody of their 7-year-old son because Lauren is deficient as a parent ... often disappearing for long periods of time to hang with celebs. We're told Andrew found out of her affair with Simon this Spring, and was shocked when he saw a pic on TMZ Friday ... showing Simon and Lauren kissing in August, 2012, on a boat HE chartered.

We're told there is a prenup and the money issues in the divorce are "minor." The real issue is custody. As one source said, aside from the fact that Andrew doesn't think Lauren is a very good parent, there's an element of revenge for being utterly humiliated.

Randy Jackson predictably sidestepped our question about his good bud "American Idol" cohort Simon Cowell.

Randy had just landed at LAX and he pretended like he was coming from Mars when we asked about the happy-ish news that Simon was about to become a daddy after secretly banging his friend's wife.

Simon Cowell is solely focused on Lauren Silverman and their unborn baby -- despite allegations of betrayal from her estranged husband ... sources close to the couple tell TMZ.

We're told Simon is saying privately that his baby will "want for nothing." He will gladly provide for the child, and not just financially. Simon is saying he will be a committed, fully-involved parent and says he wants a big role in raising the child.

As for Lauren ... people who know Simon say he's never been happier than when he's with her.

Andrew Silverman was "shocked" when he went to TMZ this morning and saw a pic of his estranged wife kissing Simon Cowell ... sources close to the former couple tell TMZ.

Our sources say Andrew had no idea Simon and Lauren Silverman had been getting it on for that long. The pic was taken on a boat where Andrew was present.

We're told Andrew feels humiliated that Lauren and his former good friend Simon had been sneaking around behind his back for so long.

Simon Cowell's FORMER good buddy claims Mr. 'X Factor' was sticking it to his wife before they parted ways ... and THAT'S why he's accusing Cowell of adultery ... TMZ has learned.

We know real estate mogul Andrew Silverman isn't buying what Simon is selling -- that he didn't lay a finger or any other part on Lauren Silverman until after the split.

There's some proof to back Andrew -- photos (above) of Lauren and Simon kissing during a yacht vacation a year ago. By the way, Andrew was also on that trip.

Andrew, we're told, just wants out of the marriage and away from Lauren and Simon, and he's willing to settle custody and financial issues quickly. For now, he's asking for full custody of their 7-year-old son, but it appears from what we know that's a negotiable point.

A source close to Lauren tells TMZ ... Lauren and her husband were over before she and Simon entered into any kind of relationship.

Simon Cowell may have committed a crime in addition to a bro sin by allegedly banging his good friend's wife ... because that, our friends, is considered CRIMINAL ADULTERY!

Who knew ... but we did some digging and found a New York law making homewrecking a criminal misdemeanor, punishable by up to 3 months in jail.

As we reported ... real estate mogul Andrew Silverman filed divorce docs in NYC, alleging his wife Lauren and Simon committed adultery during his marriage and made a love child. She's 10 weeks pregnant.

Here it is ... THE FIRST PHOTO OF SIMON COWELL'S ALLEGED BABY -- unfortunately, you can't really see the thing because it's buried inside the womb of his friend's wife.

Simon's alleged baby mama Lauren Silverman -- the 36-year-old wife of his real estate pal Andrew Silverman -- stepped out in the Hamptons on Thursday, carrying Simon's little bundle of rapidly multiplying cells in her uterus (allegedly).

As we reported, Andrew just filed divorce docs claiming Lauren committed adultery when she conceived Simon's baby.

Adultery ... the real "ex" factor.

Simon Cowell is a homewrecker -- at least according to his good friend who filed divorce papers accusing Simon of banging and then knocking up his wife DURING their marriage, TMZ has learned.

Andrew Silverman has filed divorce docs in New York and TMZ has learned he's alleging ADULTERY in seeking to end his marriage to Lauren Silverman ... who is believed to be pregnant with Simon's child.

It's pretty shocking ... in New York claiming adultery is like a legal nuclear weapon ... if proven, the cheating party (and Simon) can be forced to take a DNA test -- something that's hard to get in New York when a couple is married and the wife gets pregnant.

In the docs, Silverman, the plaintiff, lists Lauren as a defendant and Cowell as a co-respondent.

Andrew doesn't pull any punches in the divorce papers, saying, "The nature of this action is: to dissolve the marriage between the parties based upon (1) the commission of acts of adultery by the defendant and (2) defendant's cruel and inhuman treatment of the plaintiff."

Judge this: Simon Cowell impregnated his good friend's wife ... and she's already nearly 3 months along ... this according to reports.

Us Weekly broke the story, reporting Cowell is expecting a child with New York socialite Lauren Silverman, the estranged wife of Cowell's close friend Andrew Silverman, a real estate mogul.

36-year-old Lauren and her husband have been in the middle of a divorce for a while ... but still haven't severed the cord.

Lauren is reportedly 10 weeks pregnant. FYI, Simon is 53 and this would be his first child.

Lauren's got talent too ... she's pretty damn hot. And it's safe to say Simon has a type. Just check out his recent exes, Mezhgan Hussainy and Terri Seymour.

"X-Factor" producers concocted an elaborate scheme in order to GUARANTEE the failure of one H.S. Show Choir ... all for the sake of shaming them on national television, so say the alleged victims.

Members of Hollywood High School choir -- H20 -- filmed a segment for the upcoming season of "X-Factor"

But things didn't go as planned. The leader of H20 tells TMZ ... producers had a sick plan to humiliate and embarrass their crew when they appeared on stage.

They rehearsed an awesome song "Some Nights" by FUN, but at the last minute producers told them the song wasn't on the approved list. Ditto the other song they rehearsed -- "Rolling in the Deep" by Adele.

They ended up singing "Shake It Out" by Florence and the Machine ... and it was a disaster. For starters, Simon cut the choir off before they could get through the song ... because they were wearing normal street clothes instead of their uniforms. But here's the thing -- they say producers insisted that the group NOT wear the uniforms.

But wait -- there's more. The group claims they had to wait 14 hours before taking the stage, they weren't able to rehearse, and they only gave the 14 choir members 6 mics.

The group tells us ... they're demanding an apology because they feel they were purposefully humiliated.

A rep for "X-Factor" tells TMZ ... "The group had the chance of performing 2 songs for judges. The judges didn't think they were good enough to move forward in this competition."

Then adds, "Certain songs cannot be cleared for use in the show and contestants are informed of this in advance and are asked to choose alternative songs if this is the case. None of the judges even commented on what the group was wearing."

Now here's what the group sounds like .... singing "Some NIghts" at TedX in Hollywood.
