A few months ago we put you on to Post Malone and his catchy “White Iverson” track. Now, it’s gone so viral that NBA players are rocking with it—including the ones he mentions in the song’s lyrics. Last night at Kylie Jenner’s 18th birthday party, Post performed “White Iverson” with a little help from Rockets superstar James Harden.

The Beard is mentioned in the song, as Post raps/sings, “bitch I’m Harden, I don’t miss nothin’.” You can see Harden join Post on stage in the video posted to his Twitter account, below:

Party on, dudes.
