20 Celebrity Bridezillas (and Groomzillas) That Might Surprise You

In addition to signing an agreement to not drink or do drugs during the wedding, guests also had to dig deep into their wallets to get gifts from NeNe and Gregg's Neiman Marcus registry.

Jessica Biel reportedly took a backseat while JT and his mom chose the food, wine, cake and flowers. Mama's boy much?

She and Arun Nayer married in a castle in England, then went on a six-day wedding tour which included horse rides, star-studded Bollywood numbers and 13 different designer gowns for Liz. The couple also requested gifts of livestock from their guests, who had to follow a strict dress code. That's when you RSVP that you won't be making it.

Some people have traditional receiving lines to greet their guests. David and Victoria sat on matching thrones to receive theirs. Guess they were considered pop culture royalty at some point.

When the NBA star married Gabrielle Union, he made her three outfit changes look like NBD. Sure, he also changed three times, and as he told Seth Meyers on Late Night, "I came out to my own song, had my own moments."

Kim's nups to Kris Humphries, which was being filmed for television, was bananas. Kardashian and Humphries got married after Will and Kate, and Kim was trying to outdo the royal wedding in every way possible. Well, the marriage only lasted 72 days so they beat them that way.

Ye wanted make sure Kim's third time was a charm so they had three ceremonies and three dress changes for what they dubbed "the wedding of the century." Sure.

The country singer became a diva, with three different gowns (one to walk down the aisle, the second for dinner, and a third to dance in), and had the kind of detail Bey and Jay require. Calm down.

If you've ever seen a paparazzi shot of Ashley's twin sis, then you know she loves to smoke. So when she and Olivier Sarkozy tied the knot in an intimate Manhattan affair with 50 of their nearest and dearest, not only were their cocktails served in a garden but there were bowls filled with cigarettes for the guests to enjoy. Smoke 'em if you got 'em.

Before Eric Johnson, there was Nick Lachey, and their wedding featured a gospel choir, a ballroom filled with 30,000 roses, and a reality show that comes after the vows are exchanged.

The actor-comedian may have just gotten married to Laura Gallacher but during his 2010 wedding to first wife Katy Perry, he hired acrobats and jugglers to entertain guests, rode in on an elephant, and bought Katy an actual tiger as an "I Do" present. We don't.

The former co-host of The View used and abused her fame, and lost her job, after getting corporate sponsors to donate goods and services to her wedding in exchange for publicity. Considering she and Al Reynolds split after three years, it wasn't the smartest idea.

The supermodel and now-ex-husband, Jamie Hince, wanted to make sure her equally beautiful guests didn't steal any of her thunder (like many believe Pippa did with Kate) so she made them text her pics of outfits they planned to wear so she could ensure she wouldn't be upstaged.

Kevin Jonas' now-wife wanted it to snow inside the tent but their wedding planner had to educate her on why that simply wouldn't work. (Aside from, well, it BEING IN A TENT, the melting snow would make the dance floor far too slippery.) So they had to settle for a custom 12-foot ice bar with the bride's lace etched into the block.

The actress' reality show documented her plans to walk down the aisle for the third time, in which fiancé Kurt Iswarienko had to abide by her strict rules, babies were banned from the ceremony that she singlehandedly planned in seven weeks.

The Real Housewives of Miami star married Frederic Marq in a church in Coral Gables, Florida, which is where things went a little cray. Her guests had to undergo multiple costume changes and while the bride was getting her vitamin cocktail intravenously, the groom got Botoxed before walking down the aisle. A perfect match.

Longoria and first husband Tony Parker got hitched after Tom Cruise and Katie Holmes and there were reports that she wanted it to be as big a to-do as theirs was. Eva went all out and the two were married in a French chateau, but it seems she was more interested in the wedding planning than the actual marriage. But they did end up just like TomKat's marriage did, so that's something.

Before her wedding to now-ex-husband Alex Young, the actress admitted that she lost it over a bra. "The sad part was there was a mirror there so I had to see my face turn to stone, snakes coming out of my hair," she (half?) joked to Entertainment Tonight. "It was bad. I can't believe I had a meltdown over a bra."

The billionaire who made his moolah from Napster wanted a wedding "fit for a king" when he married Alexandra Lenas in 2013, so he spent around $9 million for a "fairytale-like setting," with bridges and ponds and hopefully no troll, while the guests wore custom Lord of the Rings outfits to maintain the theme.

The actress had two different bridesmaids dresses for her big day, telling People, "If I don't like one colour, then I have the other one." Rue did admit that she was getting pretty 'zilla-y, explaining, "I'm getting very detail oriented in a very O.C.D. kind of way, which is not a good thing when you can't control it." At least she owned it.
