X-Factor

Simon Cowell was sent packing Friday ... just days after his baby was born, but not because Lauren Silverman threw him out -- because a judge laid down the law in her complicated custody case.

As we previously reported ... Lauren's nasty divorce from Andrew Silverman ended with a custody arrangement for their 7-year-old son Adam, which required Lauren to keep Simon away from the kid for a year. Adam stayed with Lauren over the last few days, which meant Simon needed to skedaddle.

Simon moved into the swanky St. Regis Hotel in NYC ... but we're told he moved back with Lauren when Adam left.

As for the immediate future ... we're told Simon will stay in NYC for 4 to 5 weeks, until their baby is allowed to fly. The new family will then go to London for "X Factor" auditions. They'll be in the UK for around 3 weeks and then return to NYC.

Our Simon sources say he and Lauren will split their time between NYC and London, and since he has a plane it's no big deal.

Simon Cowell's baby mama better tighten up her lady parts ... 'cause the "X-Factor" judge just landed in New York -- and he's making a beeline for the hospital.

We broke the story ... Lauren Silverman went into labor early Friday morning -- and Simon rushed home from London to be there -- but based on his look in the pic ... the soon to be dad doesn't look too worried about missing things.

Something tells us he won't be filming the gruesome process.

"X Factor" judge Paulina Rubio doesn't take kindly to being snubbed ... in fact, she's now suing Telemundo for trying to replace her on the upcoming season of a kids-themed singing show.

Paulina -- who appeared as a coach on season 1 of Telemundo's "La Voz Kids" last year -- claims the network agreed to pay her $1.325 million to appear on the second season as well ... then reneged on the deal when it found someone cheaper to replace her with.

Paulina claims Telemundo offered up a weak excuse for the diss ... citing scheduling issues with Paulina's commitment to "X Factor" ... but she's not buying it.

Paulina wants Telemundo to cough up the $1.325 million stat ... plus another $100,000 for season 1 "La Voz Kids" clips featuring Paulina which the network sold for ad purposes.

Demi Lovato is furious at the producers of "X Factor," grousing that she was blindsided by a skit that mocked her addiction ... TMZ has learned.

Mario Lopez introduced a skit which showed clips of Demi drinking what looked like booze, acting annoying and off center.

Demi is extremely upset because addiction has turned her life upside down. It got so bad, she was living in a sober house for more than a year just to avoid temptation.

You can see her reaction on the show ... at one point it appears she says "That's f**ked up."

Demi's already said she's leaving the show, but now it's pretty clear ... for her it couldn't be soon enough.

We contacted reps for the show ... so far no word back.

Paulina Rubio's ex-husband desperately wants a piece of her "X Factor" fortune ... claiming the singer screwed him out of his rightful share of the spoils in their divorce settlement.

Nicolas Vallejo-Najera just filed legal docs, accusing Rubio of concealing financial info during divorce talks earlier this year ... stuff like her big money contracts with "X Factor" and another talent show on Telemundo.

Nicolas and Paulina settled up in March. Under the deal, Paulina agreed to pay Nicolas $6,750 a month in spousal support for 3 years -- but Nicolas now says that number was based on Paulina's low ball income estimates and now he wants more.

It's Simon Cowell's 54th bday today ... and he's marking the occasion by cleaning the TOILET PAPER off his Beverly Hills mansion.

So, who would have the balls to TP Simon's pad? How 'bout a group of 5 girls.

Sources tell TMZ ... the culprits are the ladies from Fifth Harmony, the girl band Simon signed to a record deal after they performed on "X Factor" last season.

Besides the ass paper, the gals also hung a banner that reads, "Happy 87th Birthday Simon!"

Simon Cowell is a cold-blooded killer ... of music, at least according to Sinead O'Connor.

O'Connor appeared on The Late Late Show in Ireland, and went off on the "X Factor" judge, as well as Louis Walsh -- an entertainment manager who's a judge on the British version of "X Factor."

O'Connor goes on to explain how the industry is now all about money-worship and over-sexualizing young people.

Paulina Rubio needs to have her head examined because she's frickin' crazy ... so claims her ex- husband who is trying to get a judge to order a psych evaluation on her.

We broke the stories ... Paulina and Nicolás Vallejo-Nájera have been battling for more than a year over their son. It's ultra-bitter, with each accusing the other of alienating the boy from them.

Vallejo-Najera is now pulling out all the stops. He claims she hasn't undergone a psych exam as ordered by the judge, so he now wants hizzoner to make it clear -- she better get her head shrunk, or else.

BTW ... Vallejo-Najera says he handed the tyke over to the "X Factor" judge on August 3, and hasn't seen the kid since.

Britney Spears made a fortune last year -- way more than $10 million -- but she's still a hardcore bargain shopper ... this according to new legal docs obtained by TMZ.

According to documents, Britney's conservatorship raked in nearly $14 mil in 2012. But here's the thing ... she spent $6.8 mil, which sounds like a lot, but a closer look makes Brit look like a bargain hunter.

-- $63.74 at a 99 Cents Plus
-- $11.92 at Pay 99 Cents Or Less
-- A tab from Subway, Wetzel's Pretzels, Domino's, IHOP, 7-11, El Pollo Loco, McDonalds, In-N-Out, Coffee Bean, Starbucks, and Romano's Macaroni Grill.
-- $33,959 on grooming and wardrobe -- bargain basement for a big star.

But there are extravagances as well ... like a $500 manicure. And get this -- $3,400 on XMAS lights.

Our favorite -- Britney paid $1,500 to her Kentwood, Louisiana yard boy -- aka, Jamie Lynn's baby daddy Casey Aldridge.

As For Britney's total worth ... it's a lot. The conservatorship alone now has $36.4 million. And that doesn't include a huge chunk of her net worth ... including the $68 mil she made on her last concert tour and the $15 mil she snagged from "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.
