Nicky Hilton Celebrates at Bachelorette Party With Paris Hilton Before Wedding—See Their Sexy Looks!

Plus get details about their fun-filled weekend...things got a little naughty!

How best to describe Nicky Hilton's bachelorette weekend? Oh yeah. HOT.

The 34-year-old is set to wed James Rothschild in July in London's Kensington Palace (yes, that Kensington Palace) next month and had the most epic bachelorette weekend with little sister, Paris Hilton, 31, and friends in Miami!

The festivities began on Friday. The group checked into the 1 Hotel and Homes in South Beach and donned sexy looks as they posed for pics in bachelorette party accessories—Nicky wore a tiara and a pale pink sash with the words "Bride to Be" written on them and Paris and the other women, all bridesmaids, sported hot pink sashes that read, "Bachelorette."

Nicky wore a lace, white mini dress, paired with sparkling sandals, and Paris sported a black, semi-sheer lace dress and black stiletto booties.

Let the Bachelorette weekend begin! ??. #MrsRothschild

The group also enjoyed a seafood lunch at the Seaspice restaurant on the Miami River. Before celebrating that evening, however, they all dined at STK Miami, where servers brought out shots and sparklers after their meals.
