Does she know her underbutt is showing?!

Nicky Hilton put on quite a show outside the Versace Haute Couture event in Paris on Sunday, flashing her booty in a grommet-embellished white dress with sheer panels that were strategically placed for maximum skin exposure.

The socialite paired her revealing mini with white Christian Louboutin pumps, a loose half-up 'do and a pretty pink lip.

We expect to see a skin-baring look like this on older sister Paris Hilton, but we were shocked to see the usually-conservative star showing off her bum!

Nicky is set to marry her longtime boyfriend, James Rothschild, next week at Kensington Palace in London.

"They're just perfect for each other. They're best friends," Paris told People over the weekend. "They're so loyal and they're so in love. They're the ultimate couple. They're like a prince and princess."

"I think it's important to find someone you trust and love and spent the rest of your life," she added. "I think that's the meaning of life: to get married and have a family."

After the racy dress she wore in Paris, we can't wait to see what Nicky wears down the aisle!
