She also treated her pals to 100 bottles of Champagne, a feast of sweet treats and multiple birthday cakes, including one topped with a figurine of Hilton surrounded by tiny paparazzi models snapping her picture.
Rapper Lil Wayne and DJ Tiesto provided the entertainment by playing sets for guests including screen stars China Chow, Efren Ramirez and Jesse Woodrow, as well as director Eli Roth.
Hilton took to her Twitter to share photos of her bash, writing, "So much fun! Incredible night! Best time ever."
Roth added, "Happy birthday Paris Hilton! I had an amazing time. Yes."
