Is every A-lister on the planet currently vacationing in Ibiza, Spain? It certainly seems so!

An impressive number of celebs are ringing in August with a bang, gathering their star power to come together and celebrate fashion designer Riccardo Tisci’s birthday.

Justin Bieber shared a photo of himself looking dapper in a black suit jacket posing alongside Riccardo, Kim Kardashian and Kris and Kendall Jenner. The pop star wrote: “celebrating @riccardotisci17 birthday.”

He later posted a video of none other than Kanye West performing in front of a giant disco ball on a balcony. We’re jealous we didn’t get an invite to this party!

Kendall joined in on the party pic action, sharing a photo booth shot of her, Justin and his friend Khalil exchanging kisses and pouty faces. We’re green with envy over the caption alone — “with the boys.”

If you’re unfamiliar with Riccardo or confused as to how he has the coolest guest list ever for his birthday party, then Kim’s earlier Instagram should hopefully clear things up a little.

The TV star first wished the fashionista a happy birthday with a revealing photo featuring herself on her wedding day, dressed in nothing but sheer tights and her voluminous wedding veil. (Click here to see the photo.) The significance? Riccardo designed her dress!

“Happy Birthday @riccardotisci17 I love you soooo much!!! Can’t wait to celebrate with you tonight!!!!” Kim exclaimed on the pic.

The party is just starting, so hopefully we get some other star-packed pics as the night goes on!

UPDATE: Justin never lets us down, does he? According to the singer, and this hilarious new photo, moms need loving, too! The somewhat disturbing caption reads: "@kendalljenner @kyliejenner who's your daddy."
