The 20-year-old singer shared a series of Instagram photos showing off the good times. In one pic, Bieber, who got into a scuffle with Orlando Bloom on the island days earlier, is smoking a cigar. The "Boyfriend" singer captioned the snap simply: "Celebrate."

"@kimkardashian @kendalljenner @krisjenner celebrating @riccardotisci17 birthday," the singer captioned another photo of himself with Kardashian, Kris, Kendall, and the man of the hour. Decked out in diamond accessories, Kardashian looked glam in a swank black gown.

Kendall, who shared a picture of Bieber and his best friend Khalil giving her kisses on both cheeks, looked equally as flawless with a bright red lip in a plunging neckline ensemble. The 18-year-old captioned the photo booth shot: "With the boys."

Also in on the fun was Kardashian's husband Kanye West. Bieber posted an Instagram video of the party goers going wild while West performed off a balcony.

Earlier in the day, the E! star shared a nearly naked Instagram wishing the Givenchy creative director -- who designed her wedding dress -- a "Happy Birthday." Wearing only stockings and her wedding veil, the 33-year-old captioned the snap: "Happy Birthday @riccardotisci17 I love you soooo much!!! Can't wait to celebrate with you tonight!!!!"
