Tiffany Trump rocks LBD to play flower girl at Las Vegas wedding

Here comes the ... flower girl!

A 25th birthday celebration for one of Tiffany Trump's closest friends Andrew Warren turned into one weekend to remember. The first daughter served as the flower girl at the Las Vegas wedding of "NYC Prep" reality star Peter Carey Peterson and socialite Quentin Esme Brown, with the bride and groom only revealing their plans to get hitched on the day of.

The Georgetown University law school student flashed a big smile at the world-famous Little White Wedding Chapel as she walked down the aisle in a form-fitting LBD and sky-high stilettos instead of a traditional gown. President Trump's 24-year old daughter used a teal Tiffany & Co. bag, surely a clever nod to her name, to hold the pink rose petals that she playfully sprinkled as she walked.

The future lawyer continued rocking her edgy, new haircut -- a sleek-straight look with choppy bangs styled by famed celebrity hairstylist Jose Eber.

For the rest of her wild weekend, Tiffany pulled out all the stops in the fashion department. Sexy mini dresses in an assortment of styles -- including this hot pink bandage-style number -- were seen all over Instagram. Her socialite pals also included Magic Johnson's son EJ, who she was seen hanging out with in a number of photographs.

Tiffany's Las Vegas trip was seemingly the last hurrah before she returned for her second semester at Georgetown University, with classes resuming on Tuesday. For more on the first daughter, watch the video above.
