It looks like Riccardo Tisci's birthday bash wore Kanye West out.
In a comical snap Kim Kardashian posted on Instagram Friday night, her rapper hubby can be seen laying shirtless in a plush bed, completely knocked out.
"Side chicks be like…," the Keeping Up With the Kardashians star captioned the pic, which showed her giving her best imitation of a side chick, taking a selfie in her Ibiza digs as Kanye slept soundly in the background.
Hours before, the duo suited up in all black and partied the night away at the fashion designer's Beats by Dre-hosted, 40th-birthday blowout in Spain, where they hung out with Kendall Jenner, Kris Jenner, Naomi Campbell, Justin Bieber and more.
Kanye performed at the party for Tisci, a close friend of the family and Kim's wedding dress designer, and posed for snaps with his ladylove and several other celebs at the event.
Speaking of the Biebs, the "Confident" crooner was snapped nuzzling Kendall while his pal Khalil planted a kiss on the model's cheek at the fete in an Instagram snap. "With the boys," she captioned the shot.
And that was just the beginning of the pals cozying up.
In another photo Bieber posted on his Instagram Saturday morning, Kendall, clad in a low-cut satin black jumpsuit, lounges on the singer as if she is about to kiss him.
The duo has been getting spotted out together since earlier this year, when they sparked rumors they were collaborating on something when Kendall was seen arriving to meet him at SilverCup Studios in New York City in April.
