Caught in the Act!

Also at the Neon Carnival that night: Rihanna, who was obsessed with watching a man on stilts parade around the 944 magazine-hosted bash. But once Usher arrived, the two hung out at a banquette, chatting with a group of friends. Elsewhere, Kellan Lutz, Ashley Greene and Leonardo DiCaprio checked out the carnival and thrill rides.
Lea Michele and her Glee costars Mark Salling and Chord Overstreet were sipping "purple lemonade" cocktails and chilling out poolside at the Colony Palms Hotel in Palm Springs while in town for the festival. Rosario Dawson was also poolside, and she snacked on bacon and shrimp tempura, before heading back over to the concert with her friends.
At the actual concert, Joe Jonas was joking about the extra-tight security, laughing and pretending to check people's wristbands as they exited the bathrooms in the VIP area. And that VIP section was packed: Penn Badgley sipped a beer as he watched Lauryn Hill perform while surrounded by female friends.
Katy Perry, who sported a flowy, Boho chic dress, was spotted with a 10 person entourage backstage before the Kills performed. She and best pal Rihanna were also inseparable on the festival grounds, while a T-shirt-clad Adrian Grenier was out with the masses, just tailgating with pals – away from the VIP section.
