Fresh off her trip to Cannes
, Kim Kardashian
hosted a poolside bash in Atlantic City Sunday night. The reality star, accompanied by pal Brittny Gastineau
, hosted The Pool After Dark at Harrah's Resort.
Kardashian, clad in a curve-hugging black dress
, hung out in a poolside cabana with her pals, who sipped Midori Sour cocktails. She Tweeted a photo
from the event, too.
Though the starlet kept to herself, fans went crazy for her, trying to get as close to her cabana as possible, according to a witness. But Kardashian kept her cool and left around 2 a.m. – Jennifer Garcia
