Mad Men‘s Jessica Pare was also seen looking gorgeous at the party, which included performances by Eminem and Sean Combs.

“Mannnnn…. This is kinda the dopest show idea/execution/line up ever. Shout out to @jimmyiovine @beatsbydre @rosenberg @drdre. Incredible,” Macklemore tweeted at the party.

When Eminem surprisingly took the stage, he and Dr. Dre performed “My Name Is,” “Forgot About Dre” and “Lose Yourself.” Dre wrapped up the show by thanking the guests and shared that he personally loved the music that was played and performed throughout the night.

FYI: Nicole is wearing a Julien Macdonald dress and Sillam jewels.
