Life and Style October 17th 2011

In front of 150 of their closest friends and family, former 90210 star Shannen Doherty said "I do" to longtime partner and photographer Kurt Iswarienko at a private mansion in Malibu on Oct. 15.

"Shannen, whose father passed away in November of 2010, walked herself down the aisle in a long Monique Lhuillier ruffled dress with a maroon waistband that matched a maroon flower pinned onto Kurt's suit," a wedding guest reveals to Life & Style. "The flower girls matched in black dresses with maroon accents."

The guest also reveals that the lavish touches started even before the ceremony. "Everyone was picked up at the Malibu Riding and Tennis Club and shuttled to the private estate. Then they were all taken to the ceremony by a golf cart."

Shannen even changed into a second Lhuillier number, which she described as "blush with lots and lots of tulle."

Following the ceremony, everyone enjoyed a cocktail hour outside underneath gorgeous chandeliers hanging from trees and sipped on a specialty cocktail called Yours Truly, which is ZYR vodka, Xante pear liqueur, pomegranate juice and champagne served in a champagne flute. The concoction was made especially for Shannen by celebrity mixologist James Moreland. "There was also a cigar tent for the men nearby, where guests took home cigars with Shannen's new initials wrapped around it," the guest tells Life & Style. "And the women enjoyed a 'make your own perfume' area."

As for the reception, no expense was spared when it came to party planner David Tutera's creative and elegant decor. Guests were surrounded by red and white roses and sat on chairs with ruffled bows while dining on huge rib-eye steaks that chefs grilled outside.

And since all good things come in threes, Shannon changed yet again into a tight-fitting knee-length dress with a slit up the side for the reception.

"Over a dozen musicians were set up on an orchestra stage along with a DJ," says the guest. "The bride and groom's first dance was to "My Baby Just Cares for Me" by Nina Simone, and they later cut the cake to Johnny Cash's "Ring of Fire."

The party lasted well past 2 a.m., and cameras captured the spectacular event for Shannen's upcoming reality show, The Shannen Doherty Project, on WEtv.

And while most brides seem on edge during one of the most special days of their life, Shannen was the total opposite! "She was very relaxed and looked very happy," the guest adds. "She looked comfortable and in love."

This is the third marriage for Shannen, who was previously married to Ashley Hamilton from 1993 to 1994 and Rick Salomon for seven months in 2003. But, says Shannon, she knows this one is the one: "Marriage to me is such a gigantic commitment that it's not something I'd ever go into lightly anymore," she said. "I've learned my lesson."

Congratulations to the happy couple!
