Courteney Cox and Cindy Crawford led the top L.A. social huddle of the week during a Revlon lunch at the Chateau Marmont.

In addition to Cox, the it-woman crew included localites-turned-socialites Erin Foster, the ubiquitous Jennifer Meyer, Shelli Azoff, Cassandra Grey, Erin Foster and Jaime King.

Rashida Jones and Peggy Lipton of “Twin Peaks” fame lunched in the courtyard of the Chateau with Revlon, who donated $1 million to UCLA Women’s Cancer Research at the event.

Nick Viall’s season of “The Bachelor” showed up to shoot a group date segment at the Backstreet Boys’ iHeartMedia promotional show at the Honda Theatre in Burbank Friday night (the old Jay Leno stage).
