Photos: Oprah Parties with Diddy, Mick Jagger, Kanye and Kim Kardashian

Oprah seems like an early person, so when the Queen of Daytime Talk TV and the CEO of her OWN cable network decides to stay up late, you know it's because she's having a good time.

On Saturday, Oprah hit a pre-Emmy party hosted by Jimmy Iovine in Los Angeles. While there, she hammed it up with Diddy, Kanye West, his girlfriend Kim Kardashian and iconic rocker Mick Jagger. Oprah shared her good time with updates like "Party Ovah Here!" and "My first time meeting Mick Jagger! And yes he dances like MICK JAGGER?"

Kardashian also shared a pic from the fun night out. "No big deal" she wrote next to a photo of Oprah, Kanye and Diddy hanging out on a couch.

The party was reportedly also a birthday bash for Iovine's lady friend and model Liberty Ross. Others in attendance included Dr. Dre, Brian Grazer and R. Kelly who performed. Check out photos via Oprah and Kim's Instagram in the gallery that follow.
