If Instagram goes down at some point today, we're going to have to point the finger at Justin Bieber and Kim Kardashian.

Because two of the most-popular users on the social networking service got together at a party in Ibiza last night and have been busy sharing snaps.

Bieber brushed off his recent rumpus with Orlando Bloom as he mingled with Kim, Kanye West and Kendall Jenner - among others - at a swish birthday party for Givenchy’s artistic director Riccardo Tisci.

And Biebs even went in for a clinch with Kris Jenner, who seemed delighted to have the suave-looking youngster hugging her.

And as if the presence of some of the world's biggest celebs wasn't enough of a treat for Mr Tisci - Kim also posed for a raunchy photoshoot for him, in which she was wearing just a pair of tights.

But rather than keep it private, she's shared a snap from the shoot with fans on her Instagram.

What would we do without her?
