The event: H&M threw its second annual H&M Loves Music party on Saturday during the Coachella Valley Music and Arts Festival. Party co-host Alexander Wang also announced his new collaboration with the Swedish brand. The collection will be revealed Nov. 6.
The party started around 11 p.m., giving festival-goers time to finish seeing the night's performances and make their way over to the Indio Performing Arts Center.
The scene: The space looked like a mini-Coachella stage with pulsing neon lights, more than 700 swaying bodies and a surprise performance by Major Lazer. Jesse Marco, Just Blaze and Iggy Azalea also provided tunes throughout the evening.
The outside area was transformed into a 1950s neighborhood block party with lawn furniture, picnic tables and vintage radios. Guests crowded around a retro fridge stocked with Twinkies and Oreos, and lined up to grab grilled cheese sandwiches.
An unexpected visit from the fire department interrupted the party a little after midnight, but the festivities quickly resumed after the venue was given the OK to continue.
The crowd: Most of the party attendees arrived in an Uber car straight from the festival. Without time to change, girls in cut-off shorts with backpacks over their shoulders danced with guys wearing flip flops and sunglasses on their heads.
Meryl Streep's daughter, actress Mamie Gummer, was spotted wearing H&M 3-D glasses on the dance floor, while Rosie Huntington-Whiteley walked into the party with a group of friends and slid into a corner of the VIP area to pose for some selfies. Jared Leto, Kate Bosworth, Alexander Skarsgard, Lorde, Florence Welch, Fergie, Zoe Kravitz and more celebrities also made appearances at the party.
