Paris Hilton is a married woman -- walking down the aisle and saying her "I Do's" -- with Carter Reum in a celeb-studded ceremony ... with plenty more wedding celebrations to come!
Hilton and Reum tied the knot Thursday night at Paris' late grandfather's sprawling Bel-Air estate. Paris looked stunning in an Oscar de la Renta wedding gown, and the setup was immaculate with thousands of white roses lining the aisles and a white rose arch over the couple as they exchanged vows.
Paris' sister, Nicky, served as maid of honor while Tessa Hilton, Halle Reum, Brooke Brinson, Whitney Davis and Farrah Aldjufrie were her bridesmaids. One of Paris' longtime friends, Kim Kardashian, was in attendance and helped Paris get her dress situated. Nicole Richie, who starred in "The Simple Life" with Paris was also there.
The ceremony kicks off a weekend-long worth of festivities, including a carnival-themed party at The Santa Monica Pier Friday, followed by a black and white tie event on Saturday ... so ya, there's a lot still to come.
