Kim Kardashian and Kris Humphries celebrate their one-month wedding anniversary this Tuesday -- and the memories of their blowout bash Aug. 20 in Montecito, Calif. are still fresh and fabulous!

Among the day's many, many celebrity guests (Eva Longoria, Demi Lovato, Ciara, LaLa Anthony, Sugar Ray Leonard, Melanie Brown, Kim's famous family and others), one in particular stood out, as she often does: Lindsay Lohan, who turned up at the bash with mom Dina and little sister Ali.

A just-released photo reveals the bride, 30, posing with the often troubled Mean Girls actress, 25, at the wedding reception. After she and Humphries, 26, exchanged their "I do's," Kardashian slipped out of one custom Vera Wang dress into another, this one featuring a dramatic train; in all, she wore three different Wang creations for her big day.

Lohan, meanwhile made her own headlines that day for aping the nuptial style of another high-profile wedding star: Pippa Middleton!

Lohan wore the exact same Temperley gown donned by sexy Brit Middleton, 28, at her sister Kate's royal wedding reception in London the evening of April 29. The talked-about Maid of Honor wore the floor-length, satin Arabia gown (featuring a crystal panel) in a glittery shade of green. Lohan, to honor the Kardashian-Humphrey fete's black-and-white theme, wore the frock in white, and wore her dyed-blonde hair up in a bun.
