Kanye West knows how to bring out a crowd, especially when he's in L.A. where big celebs showed up in full force ... again.

Hollywood's finest filed into The Forum Tuesday night for 'Ye's 4th visit to the City of Angels, with Pharrell, Hilary Duff, John Mayer and even Jessica Alba making appearances. Oh, and BTW ... Kim was there, too.
