Tying The Knot

Simon Cowell got put on blast when a paparazzo dared to bring up the "M" word while Simon's girlfriend, Lauren Silverman, was feet away -- and you gotta see the ex-'Idol' judge's reaction.

Truth is ... this clip is weird all around. Cowell was partying at Ago in West Hollywood after the "American Idol" finale, but did NOT seem like the guy America came to love/hate.

He talked about crappy old 'Idol' wannabes, replacing Howard Stern and even baby diapers -- and not ONE negative word from the guy ... until the whole marriage thing came up.

The Kardashian family is offended Rob never gave them a heads-up before getting engaged, but they're not that upset, because they think he's just a serial proposer and this one won't stick ... and we're getting this from sources connected with Rob himself.

We're told the Kardashians have heard Rob proclaim his undying love many times before. Our sources say the Kardashians have heard Rob gushing about former GFs Rita Ora and Adrienne Bailon -- and even told his family he proposed to both.

We should say ... we never heard a word about Rob being engaged to either Rita or Adrienne -- and it may not be true -- but we're told that's what he conveyed to his family.

We're told the feeling is that Rob just gets smitten and goes from first date to bended knee at warp speed, and it never works out.

As for Rob's point of view, as happy as he seems with Blac Chyna, we're told he feels resentment toward his family, and that they have not fully embraced his new relationship.

Rob Kardashian is a true romantic at heart, turns out ... he pulled out all the traditional stops for his freshly minted fiancee Blac Chyna.

We're told Rob set the mood by covering the room in Chyna's house where he proposed with hundreds of rose petals -- more than 500 roses died in this stunt.

Rob wasn't done ... he adorned the place with enough candles to light up a Justin Bieber concert at Staples.

Blac Chyna and her mom walked into the room with Rob in tow, when he got down on bended knee to pop the question.

Blac Chyna's response ... "Of course, baby! You know I love you!"

Rob Kardashian blindsided his family ... not giving them a heads up or even a hint about his engagement.

Sources familiar with the situation tell us, Rob went to great lengths to keep Kim and company in the dark. We're told the proposal was "aggressively on the QT."

Our sources say Rob timed the proposal to go down when the family was away. The klan flew to Vail hours before he popped the question to Blac Chyna.

If Rob Kardashian's family doesn't want to congratulate him on locking down Blac Chyna ... it's all good, 'cause the DJ at his fave strip club's got it handled.

The DJ at Ace of Diamonds strip club shouted out the newly engaged couple on Monday night. Our sources say someone on Chyna's team whispered in the DJ's ear ... and he decided to share with the club.

Check out the crowd's reaction, and how Blac Chyna put her rock on display.

The Kardashians live and breathe on social media ... but in the 12 hours plus since Rob and Blac Chyna's engagement not a single tweet, Instagram post or Facebook update about the news.

Zilch.

Snapchat? Nada.

They've all been on social media posting but have made no mention of the engagement.

For a family that thrives on the millions of followers, they've not congratulated the family's only son and brother.

Blac Chyna is one giant step closer to getting jumped in to the krew -- Rob Kardashian popped the question Monday night, and they're engaged to be married.

Blac Chyna was sporting a massive diamond ring as she and Rob went out last night to celebrate. Sources close to the couple tell us Rob asked last night and as expected, she said yes.

Chyna's mom is still in town ... and all 3 hit up Ace of Diamonds strip club to toast their engagement -- which comes after a little over 2 months of dating.

Interestingly, all of Rob's family ... his mom, sisters and brother-in-laws all boarded a plane and flew out of town yesterday for a family vacay.

As Kris Jenner's no doubt saying this morning ... Mazel tov!

Gilbert Arenas thinks it's just a matter of time before Iggy Azalea and Nick Young are all good again ... saying she'll definitely forgive the Lakers star, and the all-important bachelor party is a GO.

Arenas -- who is ex-teammates and best pals with Young -- was leaving the Clippers game when we asked his thoughts on the fate of the Iggy/Swaggy union.

As we previously reported ... the relationship is hanging by a thread with sources saying Nick is trying feverishly to fix everything destroyed by D'Angelo Russell's bro code killing video.

Check out the clip -- Arenas says he fully expects things to work out ... and is still planning on being at Young's bachelor party for an epic turn up sesh.

Might be something to what Arenas is saying ... Iggy hit up the iHeartRadio Music Awards this weekend, with the phat engagement ring Nick gave her snug on that left hand.

Jennifer Lopez, Sting and Enrique Iglesias all sharing the same stage FOR A WEDDING ... is no big deal if you're the son of a Russian billionaire marrying your 20-year-old bride!

This is insanity, but yeah ... Russian oil tycoon Mikhail Gutseriev forked out a fortune to get all 3 performers to play his son's Moscow wedding -- and the photos and videos inside put any Hollywood bar mitzvah to shame.

Here's what you need to know -- bride Khadija Uzhakhovs' dress reportedly cost about $1 MILLION, they had a 9-tiered cake that stood at least 10 feet tall, and there was nothing less than Bentleys or Rolls-Royces at the valet.

Looks like J Lo ran through a bunch of the songs she does in her Vegas show. Check it out though, audience participation was limited ... due to the language barrier.

A blushing bride-to-be is beet red with anger because she says the TV show "Say Yes to the Dress" is about to spoil the biggest reveal in a girl's wedding.

Alexandra Godino claims she moseyed into Kleinfeld -- the bridal shop where the show is shot -- back in September. She says producers approached her and asked if she wanted to appear on the show, because apparently the bride who was scheduled flaked out.

Ali said 'yes' to the show with one proviso ... the show couldn't be broadcast before her May, 2016 wedding. Her reason ... she wanted to preserve the surprise for her hubby.

Much to her horror, she recently learned the program is scheduled to air this Friday. She says she begged producers to back down and honor her oral request, but they told her to pound sand.

The Nick Young, Iggy Azalea super wedding ain't gonna be cheap ... so says Iggy who tells TMZ Sports the reason she's postponing the event instead of her tour is because she needs to make money!!

Iggy was at LAX when we asked her how the wedding planning was going -- Iggy told us Nick wants a full fledged MEGA-BASH with all of his friends ... and dude's got a TON of friends.

Iggy just announced the wedding will be pushed wayyy back -- thanks to her upcoming tour -- saying it probably won't happen until the end of next basketball season.

"The Bachelor" winner Lauren Bushnell could have fifty thousand new reasons to smile ... and all she's gotta do is slip into some lingerie.

Bushnell's been offered a year long endorsement deal from Yandy.com, an Internet leader in ladies wear. In exchange for being the company spokesperson, we're told Lauren will get a boatload of bras and panties from Yandy's new bridal lingerie line and $50k for her troubles.

Not a bad deal considering the bride-to-be has got some serious wedding expenses coming up in the near future.

It's unclear if Lauren will take the bait, but she's certainly no stranger to accepting things ... just ask all those roses.

Another starting NFL quarterback is heading down the aisle ... this time, it's Eagles QB Sam Bradford who's officially engaged to his longtime girlfriend Emma Lavy ... TMZ Sports has learned!

If 49ers head coach Chip Kelly wants an invite to star linebacker NaVorro Bowman's wedding he's gonna have to EARN IT ... so says Bowman who claims he isn't sure yet if CK will witness the nuptials.

Bowman and his brand new fiancee Mikale joined the "TMZ Sports" TV show (weeknights on FS1) when we wanted to know exactly who was on the guest list for the big event in April.

We know NFL stars like Vernon Davis and Ted Ginn, Jr. are in ... but when we asked about Chip, Bowman said the head man hadn't made the cut yet ... and he was still considering his wedding worthiness.

Mariah Carey's upcoming wedding to billionaire James Packer will be a private affair with only 50 guests on the exclusive island of Barbuda in the Caribbean ... TMZ has learned.

Sources close to the couple tell TMZ ... Mariah's planning on getting hitched this summer on the island where her soon-to-be husband is currently building a private $250 million resort with Robert De Niro.

She's only inviting a small group of friends, who will be flown in on private jets ... naturally.

No word on the exact date, but it'll likely be sometime after mid-June. She's been on a comeback after landing new management -- a sold-out Vegas stint, a new 10-part docuseries, and her first European tour in a decade ... the gig runs through May and just kicked off to rave reviews and loads of screaming fans.

We're told invitations haven't gone out yet, so Mimi could change her mind. When you're richer than God and marrying a billionaire ... everything's possible.

San Francisco 49ers linebacker NaVorro Bowman is calling it quits ... on the single life ... preparing to tie the knot with his long time GF in a star studded April ceremony ... TMZ Sports has learned.

We got NaVorro leaving Avianne & Co. Jewelers in NYC and when we asked what kinda bling he was copping in there and he showed us ... by flashing a massive rock on a lovely lady's hand.

That lovely lady is Mikale Ferguson ... a celebrity stylist who Bowman's been with since high school and is marrying in a private garden ceremony at Caesars Palace in Las Vegas this spring.

The guest list is dripping with celebrities ... Vernon Davis, Glenn Dorsey, Dashon Goldson, and other NFL stars are expected to attend ... with more names likely to pop up.

Looks like another linebacker is creeping up on you, Russell.

10:14 AM PT -- We're told the ring is 10 carats and has a $175,000 price tag!!
