The Hollywood Reporter's Nominees Night kicked off in full swing with Oscar hopefuls and top studio executives and producers filling Wolfgang Puck's Beverly Hills hotspot Spago on Feb. 10. Hosted by Janice Min, co-president/chief creative officer of the Entertainment Group of Guggenheim Media, and Lynne Segall, THR senior vp and publisher, the industry's top talent enjoyed the evening following the Academy of Motion Picture Arts and Sciences nominees luncheon earlier in the day.

Nominees Leonardo DiCaprio, Jared Leto, Lupita Nyong'o, Bruce Dern, David O. Russell, Spike Jonze, Steve Coogan, June Squibb and Frozen co-director Jennifer Lee let loose at the intimate soiree. 

Yeah Yeah Yeahs frontwoman Karen O, an Oscar nominee for best original song for "The Moon Song" (from "Her"), took the stage for a short set and dedicated the performance to her friend and frequent collaborator Jonze and "everyone here who's been a part of 'Her.'" She also played the YYYs' 2003 hit "Maps."

The entertainment continued deep into the evening with a lively set by Cee Lo Green that got many of the nominees up and dancing. Also taking in Green's performance was Puck, returning as master chef of the Governors Ball.

Earlier in the evening, a vibrant Nyong'o joked to THR that she was going to ask best original song nominee "Pharrell [Williams] if I can borrow his hat for the Oscars."
