In what some say is America’s answer to the royal wedding, David Lauren married Lauren Bush last night in a stunning ceremony overlooking the Rocky Mountains.

Lauren Bush, from now on known as Lauren Bush Lauren, wore an intricately embroidered Victorian-style gown designed by father of the groom Ralph Lauren that one guest described as “one of Ralph’s most iconic designs.” David wore a vintage Lincoln era-inspired tuxedo, while guests dressed in Western-themed black tie, featuring cowboy boots, denim and turquoise jewelry.

Guests at the sprawling Double RL ranch in Ridgeway, Colo., named after its owners Ralph and Ricky Lauren, included Lauren’s uncle, former president George W. Bush, wife Laura and daughters Jenna and Barbara, former Florida Gov. Jeb Bush and the Lauren family, including David’s sister Dylan.

Missing were her grandparents George HW and Barbara Bush, who were unable to attend because of the altitude at the ranch. Sources tell us they sent a video message played at the Saturday night rehearsal dinner, in which they said they were sad not to be able to make it, but they were thrilled that Lauren is marrying David.

The nuptials, which had a Western theme in fitting with the surroundings and the two iconic American families, began with Lauren riding in a horse-drawn carriage to a hand-crafted ceremony structure made out of the ranch’s Aspen trees. Guests watched from carved wooden benches as the sun set over the mountains and Lauren walked down the aisle, arm in arm with both of her parents, Sharon and Neil.

Following the ceremony, conducted by Cantor Angela Buchdahl of Manhattan’s Central Synagogue, guests walked to a nearby barn on a meadow. Our spy said “the barn doors swung open to introduce the newlyweds for their first dance.” The reception featured country singing by Michael Martin Murphey, with the crowd of 200 guests dancing and dining on steak from the ranch. The wedding party included Lauren’s brother, Pierce, and her sister, Ashley, as well as David’s brother, Andrew, and Dylan with her new husband, Paul Arrouet.
