Oh, James Franco, thank god you're alright! We've been so worried about you as it's been almost a full month since we last caught up with you... and you had your hair in cornrows. We're pleased to report he was back in full smirking, self-satisfied effect this weekend for the opening of Rebel, the off-site MOCA art show he curated. Though he did wear a suit to the opening reception, he didn't stray too far beyond his comfort zone as he clearly could not be bothered to run a comb though his hair for at least a full day prior to the event. Here's a look at who showed up for the Rebel debut and what the Franco-curated exhibition is all about. More»

So that's why it was so refreshing that NYLON & Hugo Boss designed their Saturday afternoon "Escape House" party to be just as epic as anything else, but still feel like a relaxing escape from Coachella weekend.
