They know how to do it up!

A portion of the Kardashian clan (Kim, Kris, Kylie and even Kanye!) were in Ibiza, Spain and got the chance to join Justin Bieber as he attended a birthday party for Givenchy fashion designer Riccardo Tisci last night.

The 20-year-old pop star has been having quite the blast in the Spanish city, that is, until he almost came to blows with actor Orlando Bloom.

Rumor has it that round 2 of the Bieber-Bloom saga almost kicked off at the birthday bash as the Pirates of the Caribbean star was headed to the party as well but was advised to leave when he arrived thanks to Bieber's entourage.

That's one way to avoid another confrontation!
