Tying The Knot

John Stamos and his fiance Caitlin McHugh are getting married this weekend -- TMZ has learned -- but they had to spend time with cops because she's the victim of a jewelry heist.

Law enforcement sources tell TMZ, Caitlin was staying at the Beverly Hills Hotel Friday when she left -- presumably for dinner -- and came back to find burglars had broken into her bungalow and stolen around $165,000 in jewelry.

What's worse ... we're told the jewelry was on loan from the Neil Lane collection, which means she's on the hook to the jeweler.

We're told Caitlin called John and he rushed over to the hotel to comfort his pregnant fiance.

Cops tell us there was no sign of forced entry.

So far, no suspects.

Screw cake by the ocean -- Joe Jonas is getting into shape by the pool before his big wedding ... and it looks like his workouts are in full swing.

Joe was seen getting his Russian kettlebell swing on Wednesday at the Bondi Icebergs Pool near Sydney, Australia -- where he seemed to be working up quite a sweat.

After his exercise, he hopped into the famous pool for a dip.

As we reported ... Joe asked girlfriend Sophie Turner to marry him this past October, and she said yes. However, a wedding date has yet to be announced.

Paige VanZant just got engaged to her MMA fighter boyfriend ... and her last name ain't gonna change all that much.

The UFC figther posted a photo Sunday of her guy, Austin Vanderford, getting on one knee to propose, with the caption ... "I said yes!!!"

The couple's been going out since at least this past summer, when she posted a photo of the two of them together in August with the caption "Mine."

Mine, indeed. Congrats to the future VanZant-derfords!

Liam Hemsworth sure looks like he's wearing a wedding ring.

Liam was tooling around Malibu Friday wearing a gold band that screams "married," but both he and fiancee Miley Cyrus have done this before.

They got engaged -- the second time around -- in 2016 and there were multiple reports the 2 got hitched since, but various people in their lives have called BS on the stories.

Paris Hilton's fiance is falling in line, and he's damn happy to do so ... at least when it comes to planning their wedding.

P and Chris Zylka were at LAX Wednesday -- jetting off to some fabulous location, we're sure -- and, for once, we got HIS take on how their big day is gonna go down. It was immediately obvious though ... his viewpoint is pretty much hers.

Chris insists they're taking a 50-50 approach, but then deferred to Paris on just about every detail. In other words ... he's a very smart guy. Meanwhile, she dropped a hint about her bridal party.

Bad news for Chris -- he might not be top dog at his own wedding.

Steve-O just might've pulled of the craziest stunt of his life ... he got engaged to his girlfriend, Lux Wright!!!

Steve-O popped the question Saturday night onstage at the end of a comedy special he was filming in Denver with his "Jackass" buddies and family in the audience, and when we got him Sunday at LAX he gave us a firsthand look at the ring he put on Lux.

If he sounds like a new man rather than the guy known for putting a black widow spider in his mouth for shits and giggles, just wait till you hear his dream wedding plans ...

Prince Harry and Meghan Markle were late, but worth the wait for their first official visit to Wales.

The royal couple arrived at the iconic Cardiff Castle Thursday in the capital city of Wales, a pretty personal visit, of course -- he was born to the Prince and Princess of Wales. The overflowing crowd was all smiles when Harry and Meghan stepped out to greet their subjects.

Afterward, H&M headed inside the castle and joined a festival to celebrate Welsh culture.

Tiffany Trump helped out a friend who wanted to get married in Vegas -- sans the romance -- so she picked up a basket baggie and started tossing petals.

In a video that's since been deleted, President Trump's second youngest kid was seen as one of the few people in attendance at A Little White Wedding Chapel Sunday for her pal Quentin Esme Brown's "shotgun" marriage to "NYC Prep" star PC Peterson. -- who, apparently, aren't romantically involved.

It's interesting that Tiffany didn't fill in as a bridesmaid -- guess the Trump name doesn't carry as much weight in Sin City as it does in D.C. right now.

Kim Kardashian and Kanye West had a casual night out Friday at the hottest restaurant in L.A.

K & K hit up Craig's in West Hollywood and they were characteristically un-chatty, EXCEPT on the way out.

Our photog asked Kim if she and Kanye would go to Paris Hilton's wedding. You'll recall, we got video of Paris a week ago saying it was a no-brainer -- she was inviting Kim to her wedding. They've had an up-and-down relationship over the years, but things have smoothed out.

Ryan Lochte's officially touched the wall ... of matrimony -- he and Kayla Rae Reid just got hitched.

According to the marriage license, obtained by TMZ, Ryan and Kayla had a courthouse wedding Tuesday in Gainesville, Florida. Ryan's dad, Steven, was a witness to the ceremony.

We broke the story ... the 6-time Gold medalist picked up his marriage paperwork last week and we were told "marriage is imminent." Turns out, it was very imminent.

The couple got engaged in October 2016 on top of a mountain and had their first child together -- their son, Caiden -- in June.

Congrats!

Ricky Martin is officially off the market -- he says he's married to Jwan Yosef, but a big celebration is still to come.

The 'Assassination of Gianni Versace' star says he and Yosef -- who announced their engagement in November 2016 -- have taken all the required steps to make their marriage official ... and he's now a husband.

Martin told E! News they exchanged vows and signed all the paperwork -- including prenups -- so all that's left now is the party, which he says is coming soon.

Congrats!

Gwyneth Paltrow is ready to consciously couple again -- aka get married -- and she's splashed the news all over her magazine.

Gwyneth and director Brad Falchuk posed arm-in-arm for the cover of the latest issue of "Goop" ... with the headline "In Deep."

The "Glee" co-creator and GP said they "feel incredibly lucky to have come together at this juncture in our lives, when our collective successes and failures can serve as building blocks for a healthy and happy relationship."

This is will be the second marriage for both. Gywneth and Chris Martin's divorce was finalized in 2016. She started dating Brad shortly after the initial 2014 split from Chris.

Ryan Lochte just went into his last flip turn before marriage, and he's racing toward the finish line ... TMZ has learned.

Sources close to the 6-time Gold Medal-winning swimmer tell us ... Ryan and his fiancee, Kayla Rae Reid, picked up their marriage license paperwork together last week in Gainesville, FL.

We're told "marriage is imminent" ... but it's unclear exactly how soon the couple will be walking down the aisle. Although the license is good for 60 days, from what we're told, they'll get it done long before that deadline.

As we reported ... Ryan proposed to Kayla on top of a mountain in October 2016, and they announced she was pregnant a couple months later.

Meghan Markle's not the only one in her family planning a wedding -- but her half-brother's might be on hold after his fiancee got busted for assaulting him.

Darlene Blount was arrested in Oregon Sunday night -- just before midnight, actually -- after what cops describe as a booze-fueled altercation. Blount was booked for 4th degree assault about 4 hours into 2018. Happy new year!

Darlene is engaged to Thomas Markle, Meghan's half-brother. They have the same father, but don't appear to be close anymore. Thomas told the Daily Mail -- which first reported the arrest -- he hasn't seen Meghan since 2011 when she moved to take her role in "Suits."

Paris Hilton and the Palms Casino in Vegas have a very special relationship ... so it's fitting they're both looking forward to a big 2018.

The Palms put up a congratulatory shout-out to Paris on their marquee this week in honor of her recent engagement to Chris Zylka ... and also plans to gift her a piece of its iconic sign when it gets replaced later this year, as part of a $485 mil property renovation.

So, why all the love? Well, Hilton's been with the hotel and casino since day 1 -- she opened it in 2001 while wearing a million-dollar dress made of casino chips.

We're told because Paris is part of Palms' history ... Palms wanted part of its history to be with her. Oh, and it says if she needs a place to celebrate her bachelorette party ... "our door is always open for you."

Paris Hilton's new fiance has been relegated to precious cargo No. 2 -- he was left eating dust after Paris and her $2 million engagement ring jumped into a waiting SUV.

This video is hilarious ... Chris Zylka was virtually kicked to the curb after the happy couple arrived at LAX Thursday night. Paris and her new 20 carat ring were already secured in the whip, and while Chris was still loading up ... the ride bolted.

NBD ... Chris plays it off pretty smoothly. Welcome to the rest of your life, bro.
