And the award for best Emmy bash goes to … Jimmy Iovine.
The music mogul and former " American Idol" mentor brought together the likes of Oprah Winfrey, Mick Jagger, Kanye West and Kim Kardashian for a pre-Emmy party and birthday celebration for his girlfriend, British model Liberty Ross, Saturday at his home in Los Angeles.
The stars seemed just as struck meeting one another.
"My first time meeting Mick Jagger! And yes he dances like MICK JAGGER" Winfrey tweeted, alongside a photo of her with the Rolling Stones frontman.
The media mogul later admitted that she was too intimidated to bust a move with Jagger. "I didn't dance with Mick. just stood there gawking!" she tweeted.
But her BFF Gayle King didn't have any trouble. Posting a photo of Jagger and King, Winfrey wrote, "Something I never imagined seeing in this lifetime…Gayle dancing with Mick Jagger!!!!"
Kardashian tried to downplay the wattage in the room.
"Oh no big deal," she tweeted, sharing a photo of herself sitting next to boyfriend Kanye West, Winfrey and Diddy.
Winfrey also posted a photo of herself sandwiched between Diddy and West, along with the caption, "Party Ovah Here! @ jimmywin81 iovine 's. Late nite with the Fellas!"
The night didn't go too late. Us Weekly reported that the last of the guests, which also included R. Kelly, Steven Tyler, Dr. Dre and Mary J. Blige, left around 1:30 a.m.
