Iovine’s throwdown attracted a gaggle of a-listers including Oprah, Mick Jagger, Diddy, Kanye West, Kim Kardashian, Brian Grazer, Dr. Dre and a bunch more.

TMZ is reporting that a star struck Oprah  gushed that she got to meet Mick Jagger for the first time (see photo below).

We hear R. Kelly put on an impromptu performance and supposedly Diddy did too.
