Tying The Knot

Wedding crashers BEWARE -- Kim Kardashian's party planning team is taking drastic measures to keep uninvited guests OUT ... with security treating the event "as if it was the White House."

Sources connected to the wedding tell TMZ ... party crashers are being treated as a serious threat ... and not only will security constantly patrol the grounds at the Montecito estate ... but we're told they'll also get support from the sky ... in the form of roaming choppers.

We're told the majority of the wedding festivities will take place either indoors or under tents to thwart the paparazzi -- because the Kardashians don't want the footage to leak out before their special airs on TV.

TMZ has obtained a copy of Kim Kardashian's wedding invitation, and it has all the makings of a fancy schmancy affair.

The wedding, which will be held on Saturday, August 20, is strictly black tie.

The ceremony will be held in Montecito, California -- near Oprah's mansion.

Of course, the bash is being thrown by Kris Jenner and her sidekick, Bruce.

Why would Jay Cutler and Kristin Cavallari break off their engagement right after her WEDDING DRESS photoshoot? We came up with 4 awesome theories ... kinda ... sorta.

Sources close to the couple tell TMZ they've been going over their favorite passages in hopes of picking a few to be engraved on their wedding bands. We're told Kim will pick a passage for Kris' ring, and Kris will pick one to be engraved on Kim's.

According to our sources ... they are each taking it very seriously and they both want to pick something "with meaning."

As we previously reported, Kim already has a bible verse engraved into her massive engagement ring.

Only a handful of people attended the shindig Wednesday -- including Craig's 18-year-old daughter, Ella, and Weisz's 4-year-old son, Henry.

NPH and his partner David Burtka have twins together, and Neil tweeted this morning the couple has been engaged for years ... just waiting for it to become legal.

According to People.com, 27-year-old Cutler proposed to the 24-year-old actress (?) during their weekend getaway to Cabo San Lucas.

A rep for Volo Auto Museum in Chicago tells TMZ they would be honored if Prince William and Kate Middleton used the priceless car as transportation for their wedding next month.

The car was purchased specifically for Diana’s visit to the Windy City in 1996 -- her last time in the U.S. before she died -- and it's been sitting in the museum since 2007.

Hef's third wedding is just 10 weeks away, but we're told he hasn't raised a prenup convo because he "actually cares" about Crystal and doesn't want to ask her to sign one.

We're told Crystal doesn't think Hef will bring it up before they tie the knot.

The joke condoms aren't affiliated with the royal family -- but that doesn't make the website's description any less hilarious ... "Combining the strength of a Prince with the yielding sensitivity of a Princess-to-be, Crown Jewels condoms promise a royal union of pleasure."

But don't sheath your sword just yet -- there's a disclaimer at the bottom of the site that reads, "Crown Jewels Royal Wedding Souvenir Condoms are a novelty condom not suitable for contraception or protection against STDs."

Baby Spice posted a pic with her ring on and the message, "Yahooooo I'm Engaged! Love you Jade! I'm a very happy lady!"

Grammer appeared on "The Late Show with David Letterman" last night, where he told Dave he and Kayte would be "getting married soon, sometime in February."

The news comes just days after Kelsey's soon-to-be-ex-wife Camille Grammer told Howard Stern that Kelsey wasn't gay, but suggested he signed on to the cross-dressing "La Cage aux Folles" because he liked women's clothes.

Romo reportedly popped the question while celebrating Candice's 24th birthday on Thursday.

Candice is Chace Crawford's younger sister and she's a sports reporter for KDAF ... the CW station in Dallas which, appropriately, first reported the engagement.

Romo is the second Jessica Simpson ex to put a ring on it recently.

Your move, John Mayer.

UPDATE: Here's a shot of Candice's ring. Well done, Romo. Well done.
