Thursday night, the only place to be was the Chateau Marmont for the Amfar Inspiration Gala. Bullock presented a tribute to the late Elizabeth Taylor and Debby Harry performed for the A-list crowd (working in her Heart of Glass hit in her set). Sinead O'Connor also sang for Farrell, Penn, Duhamel, Rose McGowan and more after a Grey Goose happy hour.

Olivia Wilde, Joseph Gordon-Levitt, and Eva Longoria (with the President):

Eva Longoria stepped on the other side of the camera for the Glamour Reel Moments series, but on the same side of the red carpet on Monday night. Making her directorial debut, Longoria debuted a short film she created based on one of the readers of Glamour's personal story. While the Glamour Reel Moments series (Zoe Saldana and Olivia Wilde also directed films) had a big premiere at the LA Director's Guild HQ (appropriate), Longoria had to dash for a more "commanding" performance -- hosting a party for President Barack Obama later in the night as the Chief visited L.A. Joseph Gordon-Levitt also dashed from West Hollywood, but he went to Beverly Hills to receive an award from his Batman co-star Anne Hathaway at the Hollywood Film Awards, happening simultaneously in Beverly Hills.

Cody Simpson:

While Cody Simpson is currenlty on tour, the teen singer was spotted on a break jamming with the wannabees from Radio Disney's version of The X Factor, N.B.T. (Next Big Thing). Caught by cameras, the meet and greet is being woven in to a Wizards of Waverly Place episode this Friday night.

Zach Quinto:

Recently "out" Zach Quinto filled up one half of a stacked first class section on a swank Virgin America flight from New York's JFK to LAX. Sitting across from him? Real Housewives of Beverly Hills' party planner Dana Wilkey. Quinto, wearing a beanie, had a fan club waiting for him at the airport on arrival.

Cassie Scerbo, Evan Ross, Jamie Kennedy:

Two party regulars, whose red-carpet appearances are usually ho-hum, both won my personal costume contest at a pre-Halloween party inside the Hollywood Forever Cemetery last night. Cassie Scerbo (as Tinkerbell) and Evan Ross (as a Moulin Rouge ghoul) both far outplayed Jamie Kennedy, who won the party pooper award at Vevo's "Six Feet Deep" party for showing up in street clothes. Another group of celebs returns to the cemetery on Monday night for Maroon 5 and Bacardi's second year of hosting the top celeb blowout in L.A. on Halloween night.
