"Let the festivities begin," indeed.
So Kim Kardashian captioned a new Instagram pic of herself, mom Kris Jenner and little sis Kendall Jenner, all dressed to the nines—presumably in Givenchy—for designer Riccardo Tisci's Beats by Dre-hosted 40th-birthday blowout in Ibiza Friday night.
All of the ladies wore black, with Kendall in particular sexin' it up in a satiny jumpsuit with a super-plunging neckline.
No wonder the fellas—such as Justin Bieber and pal Khalil—couldn't stay away.
The 20-year-old—still looking none the worse for wear following his run-in with Orlando Bloom in the wee hours Wednesday morning followed by two more nights of partying—cozied right up to the Kardashian-Jenner party, nuzzling Kendall while Khalil planted a kiss on the model's cheek and spooning mama Kris for the camera.
"@kendalljenner @kyliejenner who's your daddy," was the rather interesting caption that Bieber used for his pic with Kris.
Oh well, c'est la vie...
Kanye West, meanwhile, performed at the bash for Tisci, a close friend of the family and, of course, the designer of Kim's wedding dress.
"Birthday boy!!!" Kim captioned another pic of herself with Kris, Kendall and the Givenchy creative director.
And we expect the pics to keep on coming!
