Jimmy Iovine — Throws BALLER Emmy/BD Party

Jimmy Iovine threw the dopest party ever at his house in L.A. last night — and here”s the thing … Oprah wasn”t the big star there.

A star struck Oprah gushed that she got to meet Mick Jagger for the first time.  But it doesn”t end there — other guests included Diddy, Kanye West, Kim Kardashian, Brian Grazer, Dr. Dre and a bunch more.

By the way — Jimmy wasn”t playing a mix tape for background … R. Kelly gave an impromptu performance … and we believe Diddy did too.

The way it looks to us — this was a combo party during Emmy weekend, but also a bash to celebrate the birthday of Liberty Ross .. who he”s rumored to be banging.

Not on the list … Rupert Sanders.
