Rihanna -- Throws Insane Block Party During NY Fashion Week (VIDEO)

Rihanna hosted one of the biggest New York Fashion Week kickoff parties ever, and all her famous friends were invited.

Check out the video. Travis Scott, who's been glued to her side for the last week, was right where Rihanna wanted him when he wasn't performing. Wiz was there, Kim and Kanye, Joe Jonas and Gigi Hadid, The Weeknd, Pharrell, Candice Swanepoel ... and on and on.

It rained last night but it certainly didn't damper the crowd.
