Usher, Rihanna and DiCaprio: The Desert Was Packed With Stars This Weekend

You didn’t even have to have a ticket to the Coachella music festival to see stars; plus a “Scream” bash with Marilyn Manson

Usher pulled up in his tour bus and team Rihanna arrived in three SUV’s at the A|X Armani Exchange and 944 Magazine Neon Carnival at the Thermal Airport on Saturday night, not far from the Coachella music festival. Inside, Justin Bieber’s mentor wasn’t taking the bait to come on stage as Jesse Marco played two of Usher’s recent hits.

Wading in sea of ferris wheels, games, bars from forthcoming eatery Ra Pour, and lots of bright lights: nearly 2,000 guests, the always camera-dodging Leonardo DiCaprio, headliners Kings of Leon, Alessandra Ambrosio, and stars from “90210” and “Glee.” Outside (and later inside) nightlife entrepreneurs Brent Bolthouse and Grace Fernandez regulated hundreds at the over-RSVP’d event.

Kellan Lutz took aim at one of the carnival games on the runway-turned-midway that had adults trotting off in to the night with oversized stuffed animals. In lieu of the tired photo booth, a novel party-favor came from sponsor 5 Gum: cartoon inspired photo “flip books.”

Celebrity blogger Jared Eng (“”), who recently partnered with Clear Channel’s KIIS FM to share resources and content, shared a booth with “Sucker Punch” actress Jamie Chung.

After surprising the concert-goers with Sir Paul McCartney on Friday night, Afrojack hit the Oasis Beach Club’s massive grounds. Inside, he took over one of the cabanas with Paris Hilton.

Fashion retailer G by Guess sponsored one of several villages in the sprawling complex, bringing more than 50,000 pieces of gear (and an ice cream truck) to hand out to 1,500 partygoers at a time. At the bar, organizers offered a $2,500 bottle of champagne with proceeds going to the American Red Cross’ Japan Earthquake relief. (Afrojack/Hilton photo by Todd Williamson.)

The Lacoste Live party won the celebrity derby on Saturday afternoon. Joshua Jackson, Diane Kruger, Katy Perry, and “Twilight” co-stars Ashley Greene and Lutz, were tucked in next to the crocodile infested pool, while co-sponsor HTC extended the olive branch to guests with rival hardware like BlackBerries and iPods by giving them a place to charge alongside their own phones on display. On Sunday, Kirsten Dunst and Alexander Skarsgard checked in. Adrian Grenier (below) set his sights on a dunk tank victim at the party (Photos by Jason Strauss)

The pre-Coachella music kicked off early last week as Swede singer Robyn topped Elle’s Women in Music private concert at the Music Box in Hollywood.

The same week that Star Magazine replaced editor-in-chief Candace Trunzo, rival OK magazine threw their annual “Sexiest Singles” event at the not-yet-opened Lexington Social House on Thursday.
