The pair looked like they were having an absolute ball at their mutual friend Riccardo Tisci's 40th birthday party – sorry, extravaganza – in Ibiza this weekend, where they sipped on vodka cocktails amongst an array of A-listers. And, luckily for us, Kim and co were more than happy to share the night with the rest of the world via Instagram.
If the abundance of black outfits might seem a tad sombre for a summer's party on the Spanish Island, then it's worth pointing out that the dress code was in fact Black Subversive Glamour – well, we wouldn't expect anything less from the Gvenchy creative director. While Kim wore a billowing black silk dress, Kate went down the more revealing route, reworking a mesh dress she first wore to the Met Ball in 2013, this time around teaming it with eye-popping turquoise underwear.
Kim Kardashian brought half her family to the party, arriving with husband Kanye West, sister Kendall Jenner and, of course, mum Kris. Meanwhile, Kate was joined by good pal Naomi Campbell, the two gathering around a 4-tiered white cake where they serenaded the host with a rendition of Happy Birthday, with Kanye on the piano.
Justin Bieber, Paris Hilton, Nick Grimshaw and P Diddy were also all in attendance, with one notable absence being Orlando Bloom, who was reportedly banned from the bash by Bieber's security.
We're sure he had better place to be anyway…
