They're a member down at present as Kim Kardashian devotes her time to new motherhood.
But the Kardashian clan seemed to have found a new pal in the form of Miley Cyrus as they cuddled up backstage at the iHeartRadio Music Festival on Saturday night.
Kourtney and Khloe, along with half-sisters Kendall and Kylie Jenner, didn't appear to be batting an eyelid as they chatted to the We Can't Stop singer, in spite of her rather daring choice of outfit.
The former Disney star opted for a typically daring ensemble for the music event, baring all in a white crochet dress, with just a pair of skimpy pants and nipple covers protecting her modesty.
And although the starlet was somewhat scantily-clad, Kourtney and Khloe seemed to have plenty to say to her, and were seen enjoying an animated conversation with Miley as they hung out backstage.
Perhaps the girls were having a chat about relationships with the 20-year-old singer, after her split from fiancé Liam Hemsworth was confirmed earlier this week amid a slew of yet more criticism for her risqué performance at last month's VMAs.
