The 31-year-old hotel heiress married British billionaire James Rothschild in London on Friday.
Wearing an ivory and silver Valentino Haute Couture gown, the new bride beamed after the star-studded ceremony at Kensington Palace. Nicky's unmarried older sister Paris served as maid of honor.
Hilton began dating Rothschild in 2011 and became engaged last year during a romantic vacation in Lake Como, Italy.
This wedding was definitely more glamorous than her previous turn walking down the aisle. In 2004, she tied the knot with childhood friend Todd Andrew Meister in an early morning ceremony at a Las Vegas chapel. The marriage was anulled three months later.
