Pop-punk princess AVRIL LAVIGNE married SUM 41 singer DERYCK WHIBLEY at a private ceremony in Montecito, CA, and Wedding Compare has all the details!

Friends and family gathered at the elite 'LillyBelle' villa in the affluent community of Montecito on Saturday afternoon. About 110 guests were in attendance for the outdoor wedding. The 20-minute ceremony began at 5 p.m. and was followed by a cocktail hour and sit-down dinner under a tent on the grounds of the estate.

In an interview with ET Canada Avril said she was used to going on stage and stuff but her wedding was totally different, saying "It was more exciting. It was the biggest moment of my life." Avril's 18-year-old sister, Michelle, caught the bouquet.

At the outdoor, non-denominational ceremony, Lavigne was walked down the aisle while the traditional Mendelssohn's "Wedding March" played. The onetime "Sk8ter Girl" escorted by her father John wore a fetching custom-made, strapless ivory gown by VERA WANG with a bouquet of champagne-colored roses in her hands. The groom and his party wore tuxedos by HUGO BOSS.

Once the groom had kissed the bride, guests tossed rose petals at the newlyweds as they walked back up the aisle.

After the wedding, guests were treated to an outdoor cocktail hour before the reception, including a sit-down dinner, under a tent on the estate. In contrast to the all-white ceremony, the reception had a red theme, with centerpieces of red roses and other flowers.

The couple's first dance was to the Goo Goo Dolls' "Iris."

Lavigne, 21, and Whibley, 26, have been together for two years, and became engaged in Venice, Italy, in June 2005, while Lavigne was on the last leg of her European tour.

Before their front page split, Liza Minnelli sported a teardrop-shaped 3.5 carat diamond ring from David Gest. They followed with a wedding where even the bridal party, which included Michael Jackson and Liz Taylor, were fodder for the paparazzi. The guest list was full of a-list and b-list celebs although Liza's own sister, Lorna Luft, had "a previous engagement." My inside scoop is that David Gest missed the rehearsal dinner! No wonder the wedding didn't last long. Click here to see the wedding photos from David Gest and Liza Minnelli's wedding!

While this is Liza's fourth wedding - and many brides don't even register for their second wedding - Liza and David registered for 389 gifts from Tiffany & Co., including 12 silver platters and new flatware and crystal. But the couple did give back to their guests. Along with a lavish wedding dinner and the pleasure of hearing Natalie Cole sing, guests got personalized favors. At the rehearsal dinner, guests received heart-shaped cookies with the couple's names written on top. The theme was repeated with the wedding favors of satin candy boxes that read "Liza and David 4 Ever."

But wedding favors can be more than a typical burned CD or a scented candle. When the couple takes the time to inject their own personality into their favors (be they hopeless romantics or jokesters), there is nothing cookie-cutter about them. As seen in In Style Weddings, John Stamos and Rebecca Romijn-Stamos created kitschy air-fresheners printed with a '70s style photo of themselves and the words "our love will last forever" -- then had the valets hang them in guests' cars.

Something as simple as flowers can set the tone for the entire wedding. In Style reported that in her wedding to Brad Pitt, Jennifer Aniston chose a fresh and simple bouquet of vendella roses and green hydrangea tied with a white satin ribbon. When marrying Charlie Sheen, Denise Richards chose to carry a classic bouquet of white and ivory polo roses. Debra Messing, on the other hand, opted for something minimal and stately -- a bouquet of tall calla lilies. True to her sweet, girlish nature, LeAnn Rimes opted to carry a bouquet of roses, sweet peas, hydrangea, and freesia.

When celebs choose to have a wedding at home, they often add luxurious touches. When Barbra Streisand married James Brolin, the swimming pool was decorated with hundreds of floating candles and pink water lilies. According to Britain's Daily Mirror, Emma Thompson and Greg Wise had their wedding at home this summer – their holiday home on Loch Eck in Argyll, Scotland. The newlyweds generously gave champagne to the local villagers who came to wish them well. You might call model Mia Tyler and rocker David Buckner's wedding low-key and sort of an at home wedding - the pair wed in a surprise move onstage at dad Steven Tyler's Aerosmith concert.

Yet most celebs spare no expense, spending enough money in one day to buy the average couple 2 or 3 new homes. Aniston and Pitt's fairy tale wedding cost over $1 million, as did Beatle Paul McCartney's and Heather Mills's wedding. Purportedly, Zeta-Jones and Douglas spent between £1.2 and £1.5 million on their lavish feast catering alone cost £500 pounds per wedding guest and her dress supposedly cost £100,000 pounds. And the short-lived Minnelli-Gest wedding cost $3.4 million.

But surprisingly, what's supposedly the most expensive wedding ever wasn't a celebrity one. Multimillionaire Peter Shalson and wife Pauline spent £2 million to have Elton John perform at their wedding, plus another £6 million on opulent touches such as live parrots and the finest champagne and caviar for their 300 guests!

Want to elope?

Even celebrities can feel overwhelmed by the burden of planning their enormously scaled weddings, even with the help of wedding planners. (Look at Ben and J.Lo, current rumors are that they're planning a much more scaled-down nuptial after being overwhelmed by the planned gala event.) With all of their resources, many celebrities still fall under the charms of eloping to Las Vegas. Kelly Ripa and her soap opera star husband Mark Consuelos ran away to Sin City, as did Angelina Jolie and Billy Bob Thornton (back when they were both sporting their tattoos of each other's names). Suvari and Brinkmann eloped to California's Big Sur, supposedly disappointing her parents.

But in keeping with the typical celebrity desire to have it all, many are eloping for the more intimate vows, then returning for the media circus wedding. Ted Casablanca - the authority on celebrity gossip for E! Online - reported that Freddie Prinze, Jr. and Sarah Michelle Gellar eloped to Mexico to tie the knot in a private ceremony, before returning to the U.S. for the "official" ceremony. Liv Tyler and Spacehog frontman Royston Langdon married in Barbados with only a few friends and no parents, then returned to plan a family affair at New York hotspot Pastis.

And in the newest celebrity fad, the paparazzi are thrown off the scent with a fake, mock up wedding. Again leading the pack are Affleck and Lopez, whose original plans included hiring several decoy brides and staging fake weddings. According to Mark Armstrong, celebrity reporter for E! News, Brooke Shields and her writer husband Chris Henchy have already pulled off this stunt. While they married in a private location, they prepared an elaborate fake wedding, complete with mannequins as guests.
