It's ladies night!
The 29-year-old brunette beauty was rocking a tight sleeveless black leather dress with a stomach cutout and strappy black heels. She was also wearing her wedding ring.
Kendall opted for a mini black skirt, a white top and bright orange heels while Kylie wore a black leather dress (just like big sister Khlo)!
Looking fabulous, ladies!
Noticeably missing from the crew was Kim Kardashian, who did not participate in the festivities.
The gals also posed for photographs with arguably the biggest performer at iHeart: Miley Cyrus.
The "Wrecking Ball" singer, who got choked up earlier in the day while performing her new hit single, was the lady in white among the sisters, wearing a mesh dress with fur sleeves and black nipple coverings. Yes, pasties.
Wonder what they all chatted about?
Khloé added a photo with her sisters, posing for the cameras with big grins on the red carpet to her Instagram account with the caption: "Sisters are everything! ❤#LeatherMoment #iheartradio"
Yes, they are!
