Khloe Kardashian put her marital woes aside for the weekend -- getting glammed up for a night out in Las Vegas!
Sporting a sexy leather dress, the "Keeping Up with the Kardashians" star appeared at the iHeartRadio Music Festival in Sin City on Saturday night ... attending the event with sisters Kourtney Kardashian, Kendall Jenner and Kylie Jenner (who had newly-died jet-black hair).
And while she was clearly putting whatever issues with Lamar Odom out of her mind for the girls' night out, she was still wearing her wedding ring at the concert.
Backstage, the ladies were seen hanging out with Miley Cyrus, who was wearing almost nothing at all during the show. Rocking a mesh dress, pasties and a pair of bikini bottoms, Miley was definitely the most underdressed star of the weekend.
Check out the gallery above for all the celeb sightings at the festival -- including shots of Britney Spears, Katy Perry, Ke$ha, Adam Levine and many, many more!
